Linux On My Samsung

Since upgrading (via clean install) my Kensington wireless mouse does not work properly after using one of the function keys on my NC10.
The left mouse stops working, or the pointer periodically 'sticks'.

Same mouse worked fine in Lucid and Karmic.

Any ideas?

This is a known bug, I have tried the posted solutions but no success so far:
