Automatic "Hold on, busy" dialog makes it very hard to exit play mode if Update() takes too long

Window management


If you manage to make Update() take a "very long time" (like >3s) in play mode, then it's almost impossible to exit the play mode since the "busy" dialog keeps on popping up. "The problem is that if, and when, it pops up, and if your Update() takes too long every frame, you have absolutely no way to exit play mode. The only option is to task kill Unity".

    To solve that huge bug or something like that try this. Go edit\preferences\. Then change the value of busy progress delay to 10 or 15. You can increase this value if you are using a low-end computer.
