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.

I would not so much be annoyed if it would not render impossible to bind new keys or the selection of a plane when playing online.

After a while this happens to ALL popup windows (yes, those of the graphical user interface, not those during flight). Also those in the options or when confirming exiting the game.

Reinstalling did not help.

So I would like to try reinstalling the redist folder programs. Can somebody instruct me on this?
