I was viewing the document browser in Skydemon.I toggled to other programmes and did something else.
Some time later I ALT-TAB back to Skydemon and Skydemon is frozen
I'm pretty sure it's trying to show me the 'I'm still here' dialogue somewhere - but it's not in the foreground, so I can't click it.
I think I've had a similar problem when looking at pilot briefing in the past.
The 'I'm still here' dialogue does briefly show up in the middle of the screen, but then the document browser appears over it but won't respond.
