I have a sort of this problem with my (bluetooth) Apple Magic Trackpad.
I used to work with Standard Bandinabox 2010 and 2010a without troubles.
Today my first Biab hard disk has arrived with Windows Biab audiophile 2011. As soon as I turn on the external box my pointer gets crazy.
If I connect a wired mouse everything is OK.
I have tried different USB inputs for the external Biab Box, close and far from the case without success.
I have two other external boxes I use for back-ups and I can connect them without any problem.
Looks like the Biab box has got a radio interference source.
The problem occurs only with the Biab box and I have the Trackpad since many months.
