coherenzy modus is not working

[JohannesH]

Hi after update on MacOS 10.5.7
and
installing the avira Premium Security Suite 2009
it is no longer possible to use the coherenzy modus in Parallels 4 (german version):
Message: »change on coherenzy-modus is not possible.
The serve mouse-sychronisation was'nt started. ...«

I tried to install Parallels Tools again and again: always the same result.
Also I installed Parallels 4 again.

What can I do?
Please help.

there is no coherence mode for Mac OS X guest, only for Windows.
