That was the first thing I tried Smile

Smile

Problem is that Upp (or indeed any client app) doesn't get notified of mouse events in the title bar since it's technically a different window. The only alternative is to call XQueryPointer which has two further problems:
- Knowing the mouse state wouldn't be enough since there is no way of telling if the XConfigureNotify is from a user action. You would have to guess at the size of the decoration and see if the mouse is in it.
- It requires Server<-->Client communication, which I believe should be avoided on such a frequent event.

Please suggest any other ideas, but I'm reasonably sure it's not possible. I've spent quite a lot of time looking at this, logging events etc.
