Comment 1 Tomas Danek 2007-07-25 14:55:34 UTC 
I found steps to reproduce the IOE:
- start two sessions 
- second session stops at breakpoint, finish it using session view
- first session has empty output windows, finish it using sessions view
- you get dialog "Cannot connect to debugged process in 10s" + IOE
Comment 2 Martin Krauskopf 2007-08-08 11:50:46 UTC 
Fixed/polished in the backend. You will get message that 'process was terminated before connection was established' in
those rare cases.

yup, there's a dialog now, no more exceptions. Verified 20070813
