An invalid object is freed in Controls.DoneControls on unit finalization (candidates: FlagControl, Application, Screen, Mouse, CanvasList).

any idea how to track which object it is? it's difficult to find since which version of our software has the bug, the bug sometimes show up, and now he seem to be disapaered :S

I would also have a look for this thread: TOmzetTimerThread
maybe this is intercepting.

Also you can include FastMM with full debug mode. This should give you a report when accessing alread freed objects.

thanx for the reply. i solved it, it was a nasty bug which causes freeing non-existing objects.
