I have a similar problem, though probably not as severe as you describe. One of the 4 plastic pads on my mouse is missing and so my mouse doesn't glide as smoothly as possible. It will hang up and zoom off randomly depending on its mood. Still I am able to control the wonky behavior enough to get past 95% of the bypass mini-games the first time.
If you can try drawing a picture using windows paint and see if the mouse still exhibits odd behavior in that program as well. If so then consider buying another mouse as a good mouse is important for gaming, especially FPS games where accuracy is paramount.
Nonetheless, in ME 1 you were able to operate the frogger mini-game with either the mouse or keyboard. It seems that in most cases the programmers didn't bother to add PC amenities in ME 2 for the controls such as in the menus and that annoying bypass mini-game. Being able to use the WASD keys to move from node to node would give people another option in what is after the 4th time or so, a complete dulldrum to the game. Thankfully the keyboard works for hacking!
