Logitech VX Revolution

I struggled for a long time to use the 'back' and forward button on my mouse in some applications. Especially the open source apps seemed to not recognise the button 4 and 5.
I tried assigning key macros, so that I maybe be able to use simple copy paste actions, but this didn't work either.

I finally found the solution: Simply switch of the SetPoint software that launches with windows start. Started working like a charm right away...
