Thx 4 the reply but I don´t know how to edit the config file.
Besides the mouse works perfect in BF2.
Fh2 got it's own control.con file, meaning it says nothing for FH2 if it works in BF2.
I had a similar problem a week ago. Right mouse click wouldn't work when operating a tank or plane.
I fixed by patience and a lot of work in my config files.
Since you don't know how to fix your config files, you could create a new account and configure your settings there or reset you keyboard configuration for your current profile to default and start mapping the keys again.
