Xming renders window in the wrong place


I am using XMing to render Unix GUIs on a Windows desktop. For some reason the window displays on the Windows desktop with the titlebar off screen. It’s displayed too high up, so the top of gets chopped off. If I maximise the window or, if I resize it, then the cursor gets messed up. You have to point the cursor about 30 pixels above where you expect it to be, in order to access a menu.

Just wondering if anyone else has had this problem with Xming.
