How to set RH mouse on VNC when host is LH

[g8jvm]

Hi
on the host machine running a vnc server the mouse is LH , I have back problems and cant use a RH mouse.

However on a laptop, I can use a RH mouse as it makes no diffrence.
Is there any way I can set the mouse on the host machine to be RH when used with a VNC, but remain LH when I use the host machine directly, and not with a vnc.

FC17 64 bit on both machines

Thanks
