Description Gary Smart 2001-04-12 02:15:30 UTC 
Version 3.2 IDE is hanging randomly after 20 minutes or so of use. Problem 
experienced on three different computers: 2 x Windows 2000 (1000mhz/256mb & 
800mhz/128mb), 1 x NT4 (800mhz/512mb), all using JDK 1.3.

So far hanging has occured: Trying to compile by pressing F9, switching 
workspaces and altering global properties. No exact sequence seems to cause the 
hangs, it just happens randomly.

When hanged the mouse pointer flickers and the CPU utilisation jumps to 100% 
(Windows Performance under task manager).

It appears as if the IDE gets itself into an infinite loop somewhere at the GUI 
level.

No problems have been experienced with ver 3.1 on the same machines.

If you encounter such a problem again, can you provide us with a dumpstack?
Press Ctrl+Break in the IDE console to get it.

Comment 3 David Simonek 2001-04-17 11:15:47 UTC 
From the dump, I can see that you're using Netbeans with Windows look and feel
set. Can you verify if the same hangs appear when running with default (metal)
look and feel? Thanks.
Comment 4 David Simonek 2001-04-18 16:13:23 UTC 
One other thing, do you know which steps lead to the hang? Can you reproduce it
some way? It would help me if I could reproduce wrong behaviour to assure that
my fix works correctly.
Comment 5 Gary Smart 2001-04-19 00:05:14 UTC 
No exact sequence of steps reproduce the hangs - it just happens. 

In response to a previous comment, I've moved two machines to use the Metal L&F 
rather than Windows, and so far (period: one day) there have been had problems. 
We'll use Metal for a few days and I'll get back as to how we're going. -- 
Choice of L&F might be one for the FAQs.
Comment 6 Gary Smart 2001-04-19 00:08:24 UTC 
Correction to my previous comment: I made a typo - The move to Metal L&F IS NOT 
causing problems so far.
Comment 7 David Simonek 2001-04-20 14:23:46 UTC 
Will not be fixed into 3.2, fix is too risky.
Comment 8 David Simonek 2001-04-23 11:49:56 UTC 
Fixed in dev version. From my observation, bug appeared only in Windows L&F,
only in MDI, and only after maximalization of some floating frame, such as
editor is by default.
