[ BUILD # : 200807170007 ]
[ JDK VERSION : 1.6.0_05 ]

How to reproduce:

1) Have two wide monitors, or just pretend you have them.

2) Open Netbeans on the first monitor. Enjoy Netbean's windows system
that let you have 2 source code tabs side by side. That really rocks.

3) Take 2 source code tabs to the second screen, they will be
encapsulated into a separate window after you drop them. Group the 2
files so that they are in the same window on the second monitor.

4) Enjoy to see that Netbeans grouped them as tabbed view. Smart
isn't it? You now feel that you have all the functionalities of the
netbeans of the first monitor on the second one. That's really cool,
you think that you can fully use your 2 wide screens.

5) Now try to have them side by side in the same window.
... unfortunaly, you can't :-(

The work around to that is to have the 2 source tabs of the second
monitor into 2 different windows, but that is clear not convenient to
manipulate.

According to the statistics on the QA page, 12% of Netbeans users are
using 2 monitors, and 5% are using 3. So this problem potencially
concerns 17% of the Netbeans users.

I was wondering if I should file a bug report or a RFE, so I took a
look at the window system documentation .. and realized that it was
pretty old, and too long to read. So .. I decided to file a bug
because from the user's point of view, this is either an
implementation problem or a design problem.
