- AMouse 4.02 (updated from 4.01)

These releases include minor fixes and enhancements over their previous versions, and while recommended, they are not considered critical updates. Again, if you have updated to ArcaOS 5.1.2, you already have all of these updates. Here are the highlights of what’s new:

If you are still running OS/2 and/or eComStation systems and haven’t yet moved up to ArcaOS, this is a great reason to do so now.
