Nope. I did some googling yesterday and aparently this is an issue with W8 and the logitech mouse. Not a carrara issue. But I have only had it happen in carrara, so it must be the combo of the 3. Basically lets say I go to pan the camera around the figure, rather then move 10degerees to the left it moves 170 degrees to the right.

But then I have had the carrara camera do so really wierd things during animations too. I was trying to do a simple camera orbiting a figure animation, when I ran it the camera went off in to the nether world spinning and orbiting on some strange tangent, then ended where it was suposed to be. I finally had to put in a primative, ordit it around the figure and attach the camera to it.
