Hi all guy´s. I buyed an optical mouse for my TI Travelmate 4000 486-DX2 running MSDOS7.10. In the past I had a normal mouse working OK, but it actually dead (The cable is short circuit or breaked), but it has too much (inconfotably) sensibility (I mean sensibility to the ratio of millimetrs moved in the screen per millimeter moved the real mouse at my hand). How can I tune this sensibility (If it can be done), and how to use the scrolling wheel in DOS programs. Actually I am usin the cutemouse driver installed by the DOS itself installer. Very Thanks. If there is a possibility of several things going wrong, the one that will cause the most damage will be the one to go wrong.

Try a newer CTMouse driver: http://cutemouse.sourceforge.net/

Try MSMouse 9.01 ===================================== If at first you don't succeed, you're about average. M2

NWCC: the new version you suggested works properly. Very thanks. Best regards. If there is a possibility of several things going wrong, the one that will cause the most damage will be the one to go wrong.
