What to do if university websites seem to be not working, nothing happens when you click?

Try and get the popup blocker on your office or lab PC fixed here (if you are on Windows 7 here, you need to use the 64-bit version): choose "Run" – preferable to “Download” and "Open".
Then use Internet Explorer to try again what you were trying to do on one of our websites.
Background:
1. My users have been reporting for a while problems getting simple things done on campus websites. Last week I observed a few in their office and in the LRC being stalled by mis- or non-configured popup blocker, and not noticing the cause, being flummoxed.
2. The above little program configures the built-in internet explorer popup blocker to allow popups from websites that are part of our infrastructure.
3. It does not attempt to configure other popup blockers, whether inside or outside of this web browser.
4. The end user could also try
  1. (holding the key:) CTRL-click on the link where your web browsing fails.
  2. Or configure the popup blocker manually.
5. However, it would likely be best if this were done via GPO…

Our Sanako Study 1200 tutor is “not responding” or crashes

2013/09/11 plagwitz Leave a comment

Update: We have been advised to
1. change the Windows Color Scheme to Basic (especially removing the desktop background on both client and teacher) and
  1. set the Tutor / Preferences / to “Slow WLAN”
  2. possibly update the video driver on the teacher station, using Windows Update or, preferably, the manufacturer’s version
  3. try to replicate the problem, but keep the Sanako logs.
2. Now we are trying to replicate he issue without the teacher station frozen, so that we have access to the logs.
2 hard crashes during one class
1. The first one
  1. on “Autoscanning” (cycling screensharing connections to student PC’s)
  4. The first one took me by surprise, the computer hung completely, I could not bring up process manager nor taskkill the tutor, had to power cycle, at considerable interruption to the the class.
  5. However, here I got some problem details from windows:
The 2nd one
1. also occurred during “Autoscanning”.
2. This time, however, not the Autoscan itself brought the system down, but only when I tried to resize the autoscan window by dragging and dropping the border (video-intensive?).
3. I got a performance notification from Windows (not legible here, but something to the amount of “your computer is dangerously slow”):
4. I managed to task kill the tutor:
5. I got some more diagnostics help from Windows which notified me that my “Windows Color scheme” had to be downgraded to “Basic”:
Dell Optiplex 760 (B6CCLK1)
1. 4GB,
2. graphics chip: Y103D Card, Graphics, 256, Loop, OUGA6; original driver Video: AMD Radeon HD3450 256M, v.8.593 WHQL Vista, A05 with DUP (101 MB)
3. dual screen (1024*768 secondary, 1920*1080 primary – I remember having hard hangs on this system when attempting to drag Autoscan Windows of Sanako Stuy 1200 Tutor ver. 5.2 across 2 dual screens of the same size on Windows XP )
4. Win 7 (64bit).
No eventvwr or Sanako log data since PC was frozen…

How to work around a possible bug of Sanako Study 1200 collecting student files opening multiple explorer windows?

2013/09/09 plagwitz Leave a comment

Problem: To great confusion of my teachers, Sanako version 7 often seems to open multiple collection windows (1 per student recorded?) when collecting files, like so:
Possible Cause: From the screenshot above,
1. where only 1 collection event out of 3 shows this undesirable behavior,
2. and the 2 that did not, collected all file either under student computer name or all under student login name:
3. is it possible that Sanako has a bug which causes it to open one Windows explorer window per student file collected, if
  1. some students are displayed under their computer name,
  2. while other are displayed under their login name?
4. This is aggravated by another limitation (or bug): Students that come online after I chose show student computer names, are not affected by this setting, but display with their login name (the default).
Possible Workaround:
1. Make sure all students display under the same naming scheme.
2. This is best achieved by waiting until every student icon shows up in the classroom map before changing the classroom map student display option.
