Description ssoong 2006-12-21 15:15:36 UTC
NetBeans 6.0 Dev (Build 200612121900)
1.5.0_05; Java HotSpot(TM) Client VM 1.5.0_05-b05
Windows XP version 5.1 running on x86
=================================================

I have a number of nb windows - one main and the others detached.
The detached windows each have a few of either xml, jsp or java editor tab 
panes.

When I leave the office every evening, I leave nb on and the computer goes 
into hibernation.

The next morning (every morning) when I bring the the computer out of 
hibernation or standby (by clicking on any key) the experience is as 
psychedelic as uncovering a basketful fresh litter of puppies. They try to 
clamber over each other, pushing each other down.

The nb windows flicker as each try to be on top of each other. It never stops. 
I would stop the clambering by minimising one of them. I wouldn't know which 
one but by minimising one of them, the clambering stops.

I have to mention that I have dual displays. My sys admin had installed a 
second display card for the second display. My main nb window would be on the 
primary display screen while my detached nb windows would be on the secondary 
display screen.
Comment 2 ssoong 2007-01-02 20:30:34 UTC
It happens even when I restore netbeans after I had minimised the main 
netbeans window.
Comment 3 David Simonek 2007-01-04 14:39:40 UTC
I cannot reproduce, could you add more information? Does the error appear when
only one monitor is used? Does it depend on number/type of detached windows?
Thanks.

Did you test it under JDK1.5? I was using JDK1.5 when encountering this 
problems. I have not tested under JDK6.

There seems to be significant difference in behaviour between JDK1.5 and JDK6.

Petr Chytil, 
could you please look at this ? Thanks in advance.
Comment 6 Petr Chytil 2007-01-12 13:15:39 UTC
I am unable to reproduce it in:

NetBeans IDE Dev (Build 200701111900)
1.5.0_10; Java HotSpot(TM) Client VM 1.5.0_10-b02
Windows XP version 5.1 running on x86
en_US (nb); Cp1252

I've tried it with dual monitors, many detached windows on both monitors.
Everything is OK when computer wakes up from hibernation.

I think this is more of an issue of system resources.

I am running dual CPU + 1GB with 4 large webapps running in concert during 
debugging, one of which is open laszlo. The moment open laszlo fires up, VM 
usage went up from 500MB to 1GB+.

At times, the competition and thrashing between the various nb windows is so 
intense that nb hangs up and I have to kill both java instances (tomcat + nb) 
from the task manager. At times even task manager won't fire up and I have to 
use Windows Defender to kill the java processes.

Comment 8 ssoong 2007-02-21 21:32:17 UTC
I had my system RAM increased from 1GB to 2GB and Netbeans detached windows 
are no longer thrashing each other.
