Comment 1 vnemec 2000-11-01 10:54:59 UTC 
there is also at least one empty toolbar on workspace - it indicates fortcoming
NPE problems
Comment 2 Jesse Glick 2000-11-02 22:03:59 UTC 
I think this is fixed now, please try to reproduce in next build...
Comment 3 Jesse Glick 2000-11-06 11:39:59 UTC 
This is still broken (trunk Nov 6). I am upping the priority and severity since
it looks rather bad when the toolbars do not work. I get the NPE immediately
after clicking on the toolbar area, and two toolbars are empty.

Comment 5 David Simonek 2000-11-27 16:42:59 UTC 
I tried your reproduction case in 3.1. release and I couldn't reproduce it
(tried at least 10x). Can you test it against 3.1. release and tell me your
results? Did it appear every time or unpredictably?
Thanx.
Comment 6 David Simonek 2000-11-28 14:13:59 UTC 
After talk with Vlada Nemec, I concluded that this bug appears to be fixed both
in release and in main trunk.
Comment 7 vnemec 2000-11-28 14:20:59 UTC 
I agree with David Simonek - I am able to reproduce this bug only in [main
trunk] builds from (nb56) to (nb62) (inclusive)
Comment 8 Quality Engineering 2003-07-01 16:19:20 UTC 
Resolved for 3.4.x or earlier, no new info since then -> closing.
