Titlebar close button doesn't work

[NukemD]

The titlebar close button on several property pages doesn't work. When you move the mouse cursor over or near this button, the pointer arrow changes into a diagonal resize cursor and any sort of mouse clicking is disabled.

The minimize and maximize buttons however do work.

This is very unusual, that's just a standard window without anything special going on... I can't replicate this on any PC, could you provide some more info?

• What OS are you running?
• Do you have any software installed that might affect standard Windows behaviour?
• Does it happen on every Sledge window, or only some? (If some, which ones?)
• Is it consistent or does it only happen sometimes?

• Windows 7 Professional x64.
• Only thing I'm running that changes Windows behavior is Classic Shell.

I think I just discovered the cause of the issue, the bug only happens when said property page is on my second monitor. If the property page is on my primary monitor, the close button works fine. But if any part of it is dragged to the second monitor then the X close button will do what it does in the above screenshot.

It only seems to happen on property pages that have the normal sized X close button. Property pages that use the miniature X close button (ie. the texture page) seem to work fine on both displays.
