[Exim] Problem with eximon

Hi,

I have a problem with eximon.
After moving the mail-system from a Suse 6.1 to a Suse 7.0 system, the
eximon , which was working perfectly before over X11-connection, dies
everytime, when I select a mail with 'ShiftLeftButton'.
Also the queue will be shown twice when I press update.
I've also downloaded the last exim-stable and compile the eximon again.
Nothing, same effect.
The X11 client is the same as before.
What could I change or check else???

Regards
Wolfgang
