winbox issues on a particular pc

Hi there,
I’m having a slight issue with winbox on 1 pc. Basically when i load up any router on that pc using winbox and the window for the program is anything smaller than maximum size. I try to maximize it and the new area is all grey’d out. Inorder to get this to show correctly I have to add a current memory/cpu usage bar or uptime bar. Also the redo and undo buttons don’t show up.
I’ve tried re-downloading the program but it’s still having the same issue.

Any suggestions?

I’ve had weird issues like this on other apps caused by outdated video card drivers.

Might look for something newer and try it.
