Designer 2.1 Build: 20070830

This has happened about 5 times now in two weeks.

I will be working away, this time I saved, compared, deployed changes,
did another compare on a second driver, and suddenly get an error box,
that says See log for details.

Hit Ok, there is a second one underneath, and then I loop, and the error
never goes away, nor shows the log.

Argh! I cannot reproduce it, it happens randomly, sometimes I loose
data (did not save in the last few moments) sometimes I do not.

Where is the log to see what the error is? I have to Force Quit the app
(running on SLED 10 SP1).
