I remember something that a scrollbar has some troubles as well. Not 
freezing, but grabbing all input, so lazarus seems irresponsive.
I've seen this with other gtk apps as wel so I guess it is a gtk issue. 
When you are tracking a scrollbar using the thumb and you move your mouse 
sideways from it, sometimes the thumb misses the event that you're not 
tracking it anymore and is stays focused.
I can imagine that if such window is destroyed, everything freezes.

I said imagine, since if it is the case, it is a BadDesign (tm) of GTK.
