[VW 7.5] Drag waits indefinately for drop
 
|
Has anybody else seen these?
I've seen this about once every three weeks for several years. The image becomes unresponsive as if it is doing something. Eventually ctrl-b is pressed to find out what could possibly take so
long. The debugger shows that the image was waiting for a drop event that it would never receive. No drag had been intended, and mouse button is no longer down.
I feel bad for anyone in this situation that doesn't know about ctrl-b because they'd think their image had frozen and needs to be terminated.
Drop event processed before wait? Missing drop event? Can button-down status be checked to see if the loop should be exited?

Yes, I have seen this in 7.7 too, and perhaps even in recent dev
builds of 7.7.1 (sorry, I can’t be sure since I’ve been skipping between both).
I too have noticed it most often in Trippy. Steve From:
