Hi Petr,
Are there any new findings with the AppKit thread dump.
Thanks,

> Here is the dump of the Appkit thread and the AWT Thread. As I indicated earlier our original application does not call invokeAndWait, it uses invokeLater to make changes to the frame once the frame is created in Appkit thread. Also I see this issue with SWT 3.7.2 as well as the latest 4.3.
