PowerPoint 2010 upgrade from 2007 disables setup show display on secondary screen
- Symptom: Without hardware changes (a visualizer that seemed to enter into the equation as an AV source seems to have been ruled out as culprit), PowerPoint cannot display show from primary right screen to secondary left screen.
- Cause: Upgrade to PowerPoint 2010 from 2007, but seems really an underlying video driver limitation that has given us grieve in our – admittedly uncommon: 1024*768 on secondary, projector-connected screen, dictated by the projector – setup before.
- Workaround: Make the 1024*768 left screen the primary screen.
- Upside: this allows to project the show to the class, but teacher can still move the underlying PowerPoint presentation onto the right screen (for previewing answers. The PowerPoint 2010 upgrade did fix the PowerPoint 2007 bug that interactive animations from PowerPoint 2003 where briefly revealed on slide load before they went into the default hidden state).
- Downsides:
- Presenter view is still not possible, complains about seeing only one screen connected, even though “Check” button brings up the windows screen properties dual screen.
- The Windows taskbar displays on the left screen, so teacher staging is visible to the class when projector is on (as it always was with a single screen. Only the secondary right screen added a staging area for the teacher).
- Presenter view is still not possible, complains about seeing only one screen connected, even though “Check” button brings up the windows screen properties dual screen.
- Upside: this allows to project the show to the class, but teacher can still move the underlying PowerPoint presentation onto the right screen (for previewing answers.

- Here is the client status on one of the frozen computers in history:
- Solution: This can happend when the client cannot connect to the Deepfreeze server. Make sure that you have the current server address.

More printing problems in the LRC: How to deal with student swipe card not being read
- Problem: You get this error message "Unable to communicate with vending hardware" (when student swipes the student id card):
- Things to try: Try first restarting the print release station computer (How?). If this does not help, in the past, this has indicated campus-wide problems. Call the HELPDESK to find out more. If they confirm, post a warning note for students on the print release station.
Streaming Problems with Realmedia via RTSP from ereserves with VLC Player (and Internet Explorer. And NetOp School)
- VLC-player
- version 1.1.9, but also currently newest 1.1.11 as well on Windows CXP SP 3
- opens from IE8 and Firefox 3.6
- but is not able to play files (tested even multi) through. Rather, it nicely falls on its face, with the audio stream simply appearing to stop, mid-sentence, after 2:38 (pretty consistently – a buffering bug? A great way to slip through pre-testing).
- In the LRC, I could hardly bring the taskswitcher up, let alone (15 minutes of waiting) the task manager, to even find that vlc.exe is the culprit, with a CPU utilization of 99% solid (Ouch!).
- Not quite so bad in the office computer where it hovered slightly above 25%, maybe busying only one CPU core.
- My Google searches do not find anything quite similar.
- RealPlayer 14 to the rescue?
- In IE8, RealPlayer does not open when clicking on the web page link with the RM file which causes a dialogue to open if VLC-player is the default player, rather a strange unplayable content error..
- In Firefox, RealPlayer open and plays (and pre-buffers) the stream completely.
- Note that ereserves “download as zip” cannot serve as a workaround: gives you only the links like http://dlib4.uncc.edu/streaming/media_play.php?file=9364cb66b9e1cae26aed0f471e9eab5b, which require you to re-authenticate, even if in the same browser session, and do not redirect to the resource, neither audio nor web page form which you could launch the audio (in short, I do not get what this download as zip is good for)
- Next Problem: This may work on my office computer. In the lab we have NetOp School installed. That adds another layer of NetOp School problems which look like they can be resolved
next time the lab is reimaged. For now, use instead audio from Moodle metacourses where possible.next time I get around to design and run a Symantec-Ghost Software and File Action on the computers (all LRC lab PCs) and test the result (on PC10) which was now.

CAOS ereserves not compatible with Sanako Study1200 Webbrowser
- Last week I noticed in the LRC that I cannot open the ereserves with language learning audio files to my students by using the Study1200 Webbrowser’s “follow” feature .
- While sending the audio listing page still works, including the login page which the students get redirected to, and which, upon successful login, redirects them to the listing;
- Getting to the actual audio file launcher page fails, since this is a popup window which the Sanako Webbrowser first blocks, while redirecting the launcher of the popup to the home page
- No pressing of modifier keys seems to be able to bypass the popup blocker. Is there a setting in the Study1200 Webbrowser to modify this behavior.
Solved: NetOp School NLSP.dll prevents streaming of Real Media via RTSP on student computers
- On a NetOp School system, Realplayer 14, when trying to load e.g. rtsp://dlib4.uncc.edu:554/e_reserves/CD4French1-7.rm (from Firefox, or disk, authenticated), crashes nlsp.dll (version 6, part of of NetOp School from Danware). This is the NetOp Browser Policy IP Filter.
- The MS-windows appcompat contains this:

- NetOp support advises to try, among other things, resetting the Winsock catalog via "netsh winsock reset", which seems to work on a testmachine.
