I have not had the problem, but the mouse control setting in the control panel, may allow you to adjust the mouse pointer to respond appropriately.
1) verify you are using a valid or generic mouse driver for your particular mouse still--- evidently you had one earlier.
2) you set the options to adjust the travel and settings of the mouse, so it responds, based on your movement during the time you are on the set screen for the mouse options, under the Control Panel umbrella. Review all options, to ensure they are set as you wish. Often you can say for mouse, to go automatically, to the Command foremost on the Foreground screen, so maybe that's clicked to ensure it goes to a command at top of screen? Go through all the options to verify you say what you want to happen.
I have not seen what you describe, but given it happening to me, that is how I would attempt to resolve it. It's simplistic, but if you have not tried it, you may need to do it. If the mouse and driver are wrong, you need to install the mouse with the appropriate mouse driver. (not much more detail I can provide here.)
Good luck-
