Line Rider and Windows Seven

Hello everyone, Jam here. Hopefully some older members will remember me, as I surely do remember most of you.

Anyway, to my issue. I have transitioned to Windows Seven (Ultimate 64 bit) and am experiencing some problems with Line Rider in it. The framerate, even when processed properly is shown irregularly. It says 40 fps, and yet it seems to oscilate between 40 and 20 frames per second every few seconds. I was hoping one of you would have any ideas on how to solve this issue, if it is at all possible.

Thanks.

My father's PC using Windows 7 Home Premium 64 bit runs Line Rider fine. Are you running anything in the background, such as Steam, a C4D, or game?

It could also be a bug in Flash Player 10.1.

Well, wish you luck on getting a solution.

No, I was running nothing but Line Rider.
And I tried two different revisions of 10.1.
