Upgade warning to 9! Mouse speed and WoTs

Don't upgrade to 9 if you play World of Tanks and probably other games. The mouse is crazy fast or doesn't move at all. A version of 8 did the same thing but I was able to slow it down in the control panel, but it doesn't fix it in version 9. I've had to downgrade.

I would imagine many people have Parallels for the same reason as me. This is a ridiculous bug and I can't believe its still causing problems in version 9!

Please fix ASAP.

iMac 27" 2011 and a magic mouse

 

Its not fixed yet

 

Is there any solution for this bug? works great whit pd8 but in the pd9 mouse speed is so fast that you can't play the game.
