Sorry to hear that. Did you try using WASD/Arrow move mode?
I found that with mouse move mode, re-centering the mouse by picking it up and putting it back down would cause the star to bounce unpredictably. It helps if you only re-center your mouse on the obstacles' turn.
Also, I had a problem earlier with click move mode where the star jittered back and forth when I tried to move at very low speeds. I thought I patched it by changing the movement calculation, but it's entirely possible that I didn't.
