Prevent multiple user login to avoid “Another instance of Tutor is already running in another user’s session on this computer” by disabling fast user switching

2014/03/27 Leave a comment
  1. Problem: As reported earlier (in the Spring and in the Fall term),  for the student PCs, Sanako issues (but likely also general performance problems, and reportedly problems on classroom computers outside of the LRC) caused by multiple users being logged into the same PC – not limited to logging in from remote via MSTSC -  seem on the increase this term (this year?), also on the teacher PC, where they prevent the digital audio lab from starting:image
  2. Workaround: force restart of the computer (time-consuming, though).
  3. Solution: Avoid, better prevent multiple user login, maybe by disabling fast user switching?
    1. Registry: HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\System\HideFastUserSwitching =1, or
    2. Group policy: Computer Configuration\Policies\Administrative Templates\System\Logon\Hide Entry points=Enabled.
  4. Other considerations:
    1. Side effects: unclear?
    2. Root cause: Not enough data. Why do users remain logged in in the first place?

Getting rid of “You must restart your computer to apply these changes”

2014/03/27 Leave a comment

I am seeing this on several computers when I or students log in. To make matters worse, “Restart now” is the default selected button, and the computers are deepfrozen, which will not only lead to loss of (potentially valuable face-to-face class) time, but could even result in an infinite loop if we do not get rid of this message.

Software-based laser pointer in PowerPoint

2014/03/26 Leave a comment
  1. You can activate software laser pointer in PowerPoint by pressing CTRL and P  (= Pointer) while displaying your slideshow. Then you can draw on your show to highlight points, just like with a laser pointer – but unlike that, it cannot run out of battery power!
  2. Other keys you can press:
    1. Erase = E (unlike with a laser pointer, you have to),
    2. deActivate = CTRL and A.
  3. Other advantages: unlike some other screen drawing tools that freeze the screen (MS-ZoomIt notably), the software laser pointer:
    1. allows you to proceed through the PowerPoint presentation normally;
    2. can be saved as ink annotations, and will show up if you convert your PowerPoint to a video or play it with narrations.

Sanako Web browsing activity not compatible with modern web infrastructure (SunGard Portal, Outlook Web Access)?

2014/03/26 Leave a comment
  1. To access campus resources – here an assignment in a Moodle course – our students need to log into a SunGard portal (with SSO – a pretty common product in higher education)l, but already the redirection after login fails with this session expiration error.
    1. We could work around this problem by browsing to the target site and logging into Moodle directly.  But our students normally do not know how to do that.
  2. More problems arose when students tried to open an email in their campus OWA, in a popup window, which, however, gets redirected to the first browser homepage.
  3. This was during an “open/prevent policy” web browsing-activity, where – to keep students on task – only certain sites (social web, webmail) were blocked.., as can be seen in this screenshot: webbrowsing-prevent-policy

Save the web, with Clip to OneNote

2014/03/26 Leave a comment

No, I don’t mean save from proprietary vendors or from spies Smile – I mean: save it to your personal storage during web browsing, like so:

clip2onenote

The essence of http://blogs.office.com/2014/03/17/onenote-clipper-clip-the-web-right-to-onenote/. https://www.onenote.com/Clipper/OneNote should be useful not only for personal research on the web.

Bugs in MS-Calendaranalytics?

2014/03/25 Leave a comment
  1. Is there an Off-by-1 bug in MS-Calendaranalytics pivot chart?
    1. I am hovering (as an example) over the first name in the upper list which displays the right name as tooltip, the first name in the second listimage
    2. I guess I could learn DAX to fix this one myself, but what I have found myself doing is copy/paste the legend control from underneath, which does not exhibit this apparent bug, as a screenshot over the wrong legend (Seems strangely inadequate!).
  2. Cannot run visual basic macro because of a syntax error”imageVersion 1 on Excel 2010 (64-bit) on Windows 7 (64-bit). Restarting (Excel/Windows) made this go away.
  3. This stopped working on load from one day to the next, without the file getting saved and updated in between: System.Runtime.InteropServices.COMException (0x80070490): Element not found. (Exception from HRESULT: 0x80070490)
