Comment 1 Svata Dedic 2001-03-26 06:05:39 UTC 
Should be fixed along wih a race bug in openide (IconManager). Reopen if it
still appears in 3.2.12+
Comment 2 Jan Chalupa 2001-04-27 18:20:11 UTC 
Verified in [release32-38].
Comment 3 Jan Chalupa 2001-05-05 23:27:03 UTC 
Target milestone -> 3.2
Comment 4 Quality Engineering 2003-07-01 13:20:19 UTC 
Resolved for 3.4.x or earlier, no new info since then -> closing.
