Hello. I have a little quiz game that depends on mouse clicks. Oh, and this is on windows.

Strangely enough it seems that sometimes that button_down does not register when I click. And I checked button_down? in update for my left mouse button, and it didn't think it was depressed either.

Has anyone else ever encountered this? Is there a workaround?

No. Can you post a minimal version of your quit game that exhibits this behavior?

It's because you phail.
