[kaffe] AWT/QT bug

[Fabien Renaud]

Hi Benja,

The second programm works on my ARM machine. BTW I still have problems 
due to mouse :
Java.lang.ArrayIndexOutOfBoundsException
   at java.awt.MouseEvt.getEvent (MouseEvt.java:283)
   at java.awt.Toolkit.evtGetNextEvent (Toolkit.java)
   at java.awt.EventQueue.getNextEvent (EventQueue.java:174)
   at java.awt.EventDispatchThread.run (EventDispatchThread.java:34)

I use qte-2.3.4

Cheers,
Fabien
