Ok, to start out I'm just going to explain everything as best as I can..

I always have my mIRC client maximized, along with all of the windows maximized.

This is the second time this bug has occurred, I do not know what I was doing the first time it occurred, so I'm just going to give all of the information I possibly can.

A friend of mine had signed onto irc with his mobile irc client, so I decided to bug him a bit, I ctcp'd him, notice'd him, notice'd the channel, attempted to dcc him but the file didn't exist, msg'd the channel, talked a little bit (didn't switch any windows or anything) moved my mouse to the left (my mouse has tapping off) and boom...this happens.

how I temporarily fixed it: unmaximizing, and remaximizing the window.

It has not happened since then.

note: this is mIRC 6.35, the script is my own, everything in it was scripted by me, there are NO dll's, or ANY modifications to mIRC's GUI, the script does not have ANY functions that mess with window size, where windows go, or ANYTHING of that nature.
