Ailerons 'sticking'...

Hi, all. May already know me, thanks to my far-fetched aircraft ideas and wants...
Anyhow...
I've came across a problem, and I have no clue what caused it.
Once inside the game, while on the ground waiting to take off, I noticed that when I tilt the joystick left or right, the ailerons tilt for a moment and then snap back to alignment with the trailing edge of the wing. This is not usual--of course, we should all already know this.
Once I have taken off, the problem continues by restricting turn and roll rates--but that makes sense, with the ailerons randomly tilting and then snapping back into alignment.
The rudders, elevators, flaps, cowl flaps, tabs and trim are not effected by any of this--nor is anything else.
It should NOT do this. Why does it, and how can I fix it?
