Yes, it happens almost every time I fly, typically when there is a change in visuals, such as when I am diving down to an airfield. As I get closer to the field, there can be a slight freeze.
The freezing was so severe, I left Aces High a couple of years ago. When I returned, the instances of freezing were greatly reduced. So, today I just tolerate it.
One interesting point, though. About a month ago I was flying in formation with another bomber and I noticed a brief freeze. I quickly asked the other pilot if he just experienced a freeze, and he responded "yes." I have no idea what this might mean, except that we both experienced the phenomenon at the same time so it may not be directly related to our home hardware configurations.
