Description Peter Zavadsky 2002-03-15 08:18:06 UTC 
During Dnd there happens deadlock or temporary freeze of IDE (depending on the
jdk version used, seems the jdk1.4 just workarounds the problem using some
timeout). 
The deadlock and the freeze occures when during the DnD in process is accessed
clipboard from AWT thread.

Its happens very often, no problem to reproduce it.
Could provide stack trace if necessary (from jdk1.3 case).

There seems to be the problem is accessing the clipboard during the
DnD in process from AWT thread.

Fix:
Javadoc to clipboard doesn't say anything about such restriction, so
I'm not sure about it.
But scheduling the accessing of clipboard outside of AWT (in
ExplorerActions and CloneableEditor) fixes the problem, neither
deadlock nor temp freeze occures again.

issue doesn't apply to new window system - verified
