Need help to reproduce! Button clicks not firing

Hey everybody,

I've seen the behavior where button clicks on buttons (specifically building buttons) were not registering, but I'm having a difficult time reproducing the problem. I'm trying to find a situation where this happens and try to figure out what's going on.

If you've seen this problem, when does it often occur? When the framerate is bad? How long into the game? Does it only happen for certain buttons?

Thanks. Hope to have this fixed by the next beta.
