Hi

I am getting the following exception while I select/mode elements within a graphiti based editor.
I exactly don't know when this will happen, it happens in an unexpected manner and frizes entire application.
Exceptions seems to happen (looking at the exception trace) while redrawing/repainting something, not sure what!!! any ideas or experiences??

Best Regards
Surya

Hm, that's hard to track back. It seems some kind of asynchronous refresh is
running for an already closed diagram - at least usually that is the cause
for such exceptions, although that appears strange on move or select.

Unfortunatly the caused by stacktract doesn't go back enough the see the
cause. Are there any file modification operations involved? I'm asking
because they might trigger diagram refreshes from the background.
