More disruptive recommendations to downgrade to colorscheme basic on lab PCs despite Themeswitcher?

2014/04/03 plagwitz Leave a comment

Is this maybe what happens when Themeswitcher crashes: While the desktop background still gets changed, the Colorscheme does not get set to Basic? How to avoid the crashing FileIOException? What fileIO may a colorscheme change require?
Disruption is the least of the problem: The warning comes up when computers become dangerously slow. In the past, they have become disfunctional during these episodues and needed to be power-cycled. This has resulted in loss of assignment and assessment materials.

“Back to basics”: Need once again to default to color scheme basic on teacher computer

2014/01/27 plagwitz Leave a comment

Same problem as last term: (What made it come unstuck/unfixed?):
No Sanako screen sharing activity involved here, but MS-Community-Clips screen sharing.
Classes are moving in, and we cannot have the teacher computer slow to a crawl and eventually crash in the middle of a Sanako class, especially not when an assessment is involved.

Forced downgrade to Color scheme Windows 7 Basic since “exceeded its allowed memory”

2013/10/31 plagwitz Leave a comment

This warning and forced downgrade appeared on the teacher after starting using MS-Community Clips (which is just a GUI wrapper for Windows Media Encoder internally, which we used on the same machine successfully while it was still on XP).
The error seems slightly more informative than what we received earlier, but I did not manage to investigate since this was in the middle of supporting a teaching use .

Switch to Color Scheme Basic not working for students

2013/10/25 plagwitz Leave a comment

Works for me:
Does not work for students for whom it primarily has to work:
Strangely, student seems to be not stuck on the original, but on an unsaved theme:

Sanako screen sharing is now too slow for the client machine..

… So that clients get suggested to downgrade to basic color scheme, in the middle of class. I saw this for the first time recently , after upgrade to Windows 7 and study 1200 version 7, on the teacher machine, same 4yr old dell optiplex 760.

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…
