SNIP! To how good the 2.0 M$mouse compatiable with mouse drivers, I used that IBM mouse driver that supports either: busmouse, serial and PS/2. OLD! but very tiny 10K and rock-solid driver on that one and worked. But I hate 2.0x at any rate due to comfort and requires stupid frequent cleaning! So often every week or so where I have not did one for weeks on my mitsumi and much better in comfort of holding that mouse. Just a comment. Jason D. PS: i have the busmouse msmouse version, (dovebar shape with feather light switches). Tis' one is nice too but too bad fouled up in 2.xx versions. Don't brother with cheapo mouses that has brass rollers (some usually are chromed) Rubber and human oil/acid/sweat salts corrodes those very quick in at least a year or so. Either Stainless or smooth-mirror not flat/matte (that causes rapid build up) plastic rollers. email: jpero(a)cgo.wave.ca Pero, Jason D.
