xfce - bug with http-authentification

[Ekkard Gerlach]

Hello,

I'm using xfce-3.8.0, Suse7.2 . 
The browsers mozilla and
NN6.2  are crashing xfce with mouse right button 
klick only after http-authentication with one or 
both browsers. 

With 50% likelyhood X crashes after mouse right 
button klick somewhere on the screen on any 
virtual desktop.

Without authentification both browsers are stable
 - as stable as NN4.7x and opera60 Beta. 

With KDE 2.1 I have no problems. No Crashes. 

If once again nobody in this list has a 
solution, I will unfortunately return to KDE
because I have to work !

thx
Ekkard
