Using Skydemon 3.15.1.0 on windows, I'm reading some documents. So I click on the documents, the popup window opens, and I slowly go through the various docs I want to read. A few times, skydemon was 'hanging' when I came back to the document browser. Whatever I do, windows beeps at me as the window is not active.

I think what happens is that skydemon tried to open the 'are you still there?' popup, that failed (at least I don't see it), but the document window, and the main skydemon window both refuse all input (my guess: because the AYT-popup took the input away) . alt-f4 is also not working.

When I open the taskmanager to stop SD, and restart, everything is back to normal.
