Comment 1 _ gtzabari 2001-09-14 20:36:11 UTC 
Gives "cannot attach. Check parameters and try again" so I can't 
attach as long as this bug is open. Increasing priority to P2 as this 
is (basic) functionality that worked before and has broken recently.
Comment 2 Jan Stola 2001-09-17 11:03:35 UTC 
I am sorry, I cannot reproduce this bug. I tried both SDI and MDI
modes with both socket and shmem transport. From the stack trace
one can see that there are some problems with Output window.
So, it seems to be unreproducible bug in Window System/Output Window.
If you are still able to reproduce this bug, please, reopen it
and we will move it into Core.
