RE: [albireo-dev] Old SAS code interaction with Albireo project code

Okay; thanks for the response.

I'll utilize a more simple case to see if I can reproduce with stack
traces.

It's worth mentioning that the focus issue may be a consequence of the 
lock-up, so that's the problem that I am most curious about.

Even if you could get us stack traces from just the SWT and Swing 
threads, that could be very helpful.

And.. as Bruno has mentioned elsewhere, make sure you are not using the 
AWT invokeAndWait or the SWT syncExec from the other toolkit's event 
thread. That's the most common cause of deadlock.
