A DESCRIPTION OF THE PROBLEM :
When trying to move between JInternalFrames using Ctrl+Alt+F6,
nothing happens.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Repeat-by:
o compile program
o start program
--> program shows two top-level windows, each containing a desktop
        with two JInternalFrames, each containing one JTextField
o klick in window 1 in a textfield
o press CTRL-ALT-F6 to select the next JInternalFrame
--> the next internal frame is selected
o klick in window 2 in a textfield
o press Ctrl-ALT-F6 to select the next JinternalFrame
--> nothing happens; the next JInternalFrame is not selected


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
I expected to be able to move between the JInternalFrames.
ACTUAL -
Could not move between the JInternalFrames.

REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
BasicDesktopPaneUI uses a cache for InternalFrames. This cache is declared static but used to hold info for a desktop instance only. If you have two desktops d1 and d2 with the same number of InternalFrames, the current
InternalFrame (in d2) is not found in the cache (containing InternalFrames from d1).
