For Doddsredoubt:
Try booting your computer into Safe Mode. (Press F8 during the boot-up phase). That will load the default mouse driver so, with a bit of luck, you should be able to get it started.
Then run System Restore (from Start > Programs > Accessories > System Tools) to take the registry back to a date before you downloaded Drive Max.
For DaisyNonna:
Pressing 'tab' advances the cursor to the next field. For instance if you've got a 'username' and 'password' field to fill in on your screen, pressing 'tab' after you've typed your username moves the cursor directly to the password field. When typing a Word document you can set tabs so that you can keep text lined up vertically:
