Event handling stops for no reason? [message #70010]

Dear all,

I have some quite strange behavior with a GUI.

Basically, event handling stops for seemingly no obvious reason. It is
resumed as soon as I move the mouse cursor over the GUI area. The
event which is in the cue, is then executed immediately.
It is quite a complex program which processes images and sends an
event to the event handler as soon as a certain step is finished. The
next processing step should then be initiated by this event. But, it
simply stops until I move the mouse, as described above.
I was unable to find a cause for such behavior. From what I have
figured out, this does not occur when the mouse cursor is permanently
over the GUI.

Any idea what could be causing this?

I am using IDL 7 on a Vista system.

Cheers,
Michael
