Urgent help needed with gui

[PissyChrissy]

I've encountered this problem too, with varying severity in various patches. Most of the time, when an option box appears (for example, do you want to quit? etc), the buttons on the box are not mouse clickable. I get around it by simply hitting "Y" or "N" on the keyboard, or tabbing around the boxes and pressing "enter", but it's still annoying.
