I am using a Tracker in Windows and everything is OK so far.
As soon as I use a Suse Linux distribution (KDE)I get some strange
behavior of this tracker. I am using a NX Client, to connect to this
Suse maschine.
The tracker is going to resize itself, like i move the mouse (what i am
not doing)
Has anybody else been confronted with this ? And if so, how did you
solve it ?
THX
Andreas

Sorry for the late reply.
I just created this Snippet for you. Hope you can reproduce the behavior.
Thanks
