SUMMARY

Setup with: "Show only windows of the actual screen" =YES

When coming back from "Standby" and log in.
The "Task Manager" shows no window.
When changing to
"Show only windows of the actual screen" = NO
then windows of all screens are shown - correct.
Switching back to
"Show only windows of the actual screen" =YES

Again no window is there - but there are Windows on this screen.

When using ALT-TAB the correct list of windows is shown.

Workaround:

If I delete the applet and add it again the correct Windows are shown!
