Description jasonhh0310 2005-04-19 21:47:02 UTC 
When running in SDI mode with the Favorites, Files, Navigator & Projects windows open either 
individually or grouped in a single window, the following exception is thrown when the mouse rolls 
over or selects the window tab. This occurs in the latest daily build in 4.1, but is a recent regression as 
it doesn't occur in the 4.1 Beta release.

Comment 3 Milos Kleint 2005-04-20 08:05:20 UTC 
fixed in trunk, quite simple fix. QA please consider it this shall go to 4.1
branch as well.
Comment 4 Marian Mirilovic 2005-04-20 15:53:34 UTC 
too late, but I vote for .... Honza, Martin ?
Comment 5 Jan Chalupa 2005-04-20 16:13:34 UTC 
P1? Are Mac users likely to be switching to the SDI mode frequently?
Comment 6 jasonhh0310 2005-04-20 18:19:14 UTC 
Have a dual 17" monitor set up, so SDI mode is very useful to move all the
palette windows to the 2nd monitor, removing clutter and allowing a larger
editor window without having to hide/minimise everything else.

This is also the main reason why I don't use Eclipse. As the last time I tried
it, it won't allow you to drag windows out of the main frame and onto a 2nd screen.
Comment 7 Jan Chalupa 2005-04-20 18:26:31 UTC 
jasonhh0310, your case sounds convincing to me. :-)

Milos, please prepare an integration into release41. If there is another RC
build, it should be able to make it.
Comment 8 Martin Balin 2005-04-21 08:44:19 UTC 
Agreed, it can go into 4.1.
Comment 9 David Simonek 2005-04-21 10:05:08 UTC 
Diff reviewed, OK, simple, just null check.
Comment 10 Milos Kleint 2005-04-22 07:56:21 UTC 
merged to 4.1 branch
