OS - AMD SLES 9
Browser -MZ1.7

Steps to reproduce :

1) Install 1.5.0 b-63 in the machine

2) Register plugin with Mozilla 1.7 browser

3) Invoke the SwingSet2 demo in the browser

4) Click on the menu, Look and Feel, and try to change the L&F to "Motif L&F" or "GTK Style L&F"

5) The Look and Feel does not change. Instead the demo whose tab is right under where you click gets launched.

The L&F can be changed by using "shift+F10"

This problem is only seen on AMD SLES9/ MZ1.7. It is not there on Redhat Advanced Server 3.0/ MZ1.4.2. Also tested on Solaris x86 5.10 JDS, and the problem is not there.

Also the problem is not reproducible with appletviewer.
