maybe it's caused by palette itself. 
Davide. please, evalute and reassign if necessary.
Comment 3 David Kaspar 2006-09-12 15:29:10 UTC 
This bug is caused by deadlock in locking of CloneableEditoSupport vs. Nodes.
To reproduce it, the VisualMIDlet has to be opened, the JavaInfrastructure has
to be parsing the file.
The JavaInf locks the Nodes Mutex first and then asking to Designer. The
Designer closing locks the Designer first, then invokes the refreshing of
Palette which is asking for Nodes Mutex. Therefore the deadlock happened.

Possible fix is to postpone the "invocation of palette refresh" using "invokeLater".
Comment 4 David Kaspar 2006-09-12 16:21:43 UTC 
Fixed in "dev". Leaving as "New" since the bug should be fixed in 5.5 too.
Comment 5 David Kaspar 2006-09-14 14:36:33 UTC 
Fixed in NB 5.5 too.
Comment 6 Lukas Hasik 2006-09-26 14:10:43 UTC 
verified in latest 5.5 build. It's hard to reproduce... I'll reopen if it
appears again, of course
