How to Right click on a PC - using mac mouse

I'm using a mac mouse on a PC and am unable to right click.
The usual ctrl Click doesnt work on a Pc and shift F10 Is not user friendly,
any ideas? I have heard of a patch type thing that allows windows to use ctrl click but so far i havn't found it.
Any help would be much appreciated

It not the mighty mouse though... i think its the model just previous

Aww that looked really promicing but it turns out its not vista compatable, one of many things wrong with vista imo

haha yeh I'm going to the shop today it was just really annoying me last night

thanks all
