Comment 1 Milan Kubec 2004-10-13 13:00:02 UTC 
Reassigning for evaluation.
Comment 2 Martin Matula 2004-10-13 16:31:23 UTC 
What build are you using? Can you provide steps to reproduce?
Comment 3 wulgar 2004-10-13 20:26:52 UTC 
I use build 20041012 but at home I'm not able to reproduce it. I
notice only that green tab which showing current execution line is
missing after fix.

Now I've got totally unusable IDE - screen will be attached with no
Exception and deadlock - I will attch log too.
