Dizzy moments
 

I'm wondering if anybody else has experienced this? When I'm in base prior to starting a mission I go to the map to plot my course. After a few moments it seems the FPS freezes then suddenly everything spins. It doesn't matter where I go to on the boat the view spins constantly. I then try to exit the game but each yes/no choice the cursor flashes over yes and no very quickly. I end up having to crash the pc and reboot.
It has only happened twice, but is very frustrating. I have run malware scans and virus scans, have defragged (and do this once per week).
Anybody know, 1, what causes this, and 2, if there is a simple way to remedy this without crashing the game?
I am hoping one of the 'Gurus' here may know how this happens
Cheers guys

what mods are you running... sounds like a mouse issue?

^^ I have not experienced a problem like you described, yet, I've had video card problems with my browser when I haven't checked for driver updates from the maker's website. My computer has an AMD video card.
I'll check the website http://www.amd.com/en-us every once in a while for updates.
