Magic Mouse problem under lion...it´s jumping ...

hi there

i got a big problem with my magic mouse after installing a new audio interface (RME BABFACE) .... after installing and restarting the system, the magic mouse jumps to corners and clicks even when I don´t push "click" on it... it goes totally crazy.... you can´t work with that... t

on my mac book pro the magic mouse works perfect !! ... so it is a software thing...definitely

i repaired the hard drive permissions and checked them also.... no success.

anyone has an idea or did had some similar problem ?

i also started a thread in RME forum but no answer so far... 😟

my system is mac mini i7 with lion 10.7.4
