Ui Window Closes With No Reason

[barbq]

Hi,

My UI window closes without a reason. It happens for almost any Maya action.
For example a button on the UI which deletes an object will work but close the UI.
A creation of a sphere from the Maya menu will work but will also close the UI.

I can't seem to understand where this is coming from.. what could cause a UI window to close??

Thanks

Found it. The context was changed, and the UI window was a context-driven UI.
