Description Yan-Fa Li CLA 2006-03-01 16:40:57 EST 
I just upgraded to 3.1.2 and I'm noticing an odd behavior on Windows XP.  I have a dual screen setup running in separate screen mode, rather than stretch desktop.  When I stretch eclipse workbench to cover both screens it works fine.  When I lock the desktop and come back and unlock, Eclipse automatically resizes the workbench to exactly ONE screen, losing my stretch settings.  This is extremely irritating and regression, which it did not do in the previous versions.

How to Repeat:
1. On a two screen desktop system.  Stretch the Workbench screen to cover both screens.
2. Hit CTRL+ALT+DELETE and lock the screen
3. Unlock the screen using password
4. watch as your workbench has been resized to the first primary screen

Could you please return the behavior to what it used to do, which is stay resized between screen locks?

Verified as described in I20060223-1656. Over to you Mvm.
Comment 2 Michael Van Meekeren CLA 2006-03-06 14:00:16 EST 
eric do you mind taking this as you have a dual monitor?  At least to investigate?
Comment 3 Eric Moffatt CLA 2006-03-07 09:00:55 EST 
Mvm, This appears to be a platform problem...same thing happens with a standard windows browser...

Should I close it?
Comment 4 Michael Van Meekeren CLA 2006-03-07 09:32:30 EST 
yup, or perhaps hand off to SWT to verify that they believe this as well and can not do anything about it
Comment 5 Eric Moffatt CLA 2006-03-08 14:17:21 EST 
OK, I'll pass it on.

SWT-folk, is this foxable in any sensible manner?
Comment 6 Steve Northover CLA 2006-04-04 11:52:59 EDT 
VI to confirm this behavior.
Comment 7 andy dingfelder CLA 2007-05-23 16:45:32 EDT 
I think this is a duplicate of 110144.

I also disagree with comment 3 (from Eric) if I am reading this correctly... I assume that comment means that if I span a browser (ie or firefox) across 2 or 3  windows, it will resize on screen saver activation?  if that is what he means, then no, it does not do that.  (neither IE of firefox has the bug, only eclipse as fas as I have seen)
Comment 8 Steve Northover CLA 2007-06-18 13:39:05 EDT 
Eric claims that IE does this.  In any case, SWT doesn't do anything when the screen saver kicks in.  Eric, can you confirm that the ControlExample has this behavior?

Closing for now.  Reopen when we have more information.

I retested this issue on XP Pro this morning, and found:

It occurs with both 3.2 and 3.3RC4
It also occurs with both IE 6.0 and Firefox 2.0.0.4

so, I retract my earlier statement that this was an "eclipse only" issue.

What I observed is that this does not occur on a screen saver startup, it only occurs when the screensaver also locks the screen.
