Annoying win key problem

[Marcelo Magno T Sales]

Hi, folks

There's a problem with the win key in FC5 which is annoying me since I 
migrated from FC4. In Fedora's KDE 3.5.1 and later in kde-redhat's KDE 
3.5.2, when I logon, the win key doesn't work as it should.
When I press win+C, for example, it looks like these keys are "sensed" 
by KDE as two separeted keypresses instead of one "combo" keypress. I 
can see this when I try to configure a new shortcut using the win key. 
When I press it, the shortcut field shows "win+", but when I press 
the next key (while holding win), the shortcut field shows only the 
second key pressed and not the combination win+key.
Then I open Regional Settings in Control Center and undo and redo my 
keyboard configuration several times until it starts to work again. 
It remains working as far as I don't log out. After the next log in, 
the win key may or may not work, apparently randomically.
This strange behavior didn't happen in FC4 with KDE 3.5.1 and below.
I use a brazilian ABNT2 keyboard, don't know if this problem occurs 
with others keyboard layouts.
I believe the problem is not in KDE, since it didn't happen in FC4 
with the same KDE 3.5.1. However, the win key work after I change and 
unchange settings in Control Center...
Any clue about why is this happening, or at least where I can start 
researching this? Don't know where the problem may be and I have 
three FC5 machines with the same behavior. 

Thanks,

Marcelo
