I have a Logitech C9 series mouse [3-button, old] at home that I use w/my DOS PC. This summer my BSD box came home with me, and being sick of the $7.99 3-button feels-still-as-hell-cheapo mouse that I have been using, I figured I would hook up the nice Logitech mouse to it... The result: same problems as described above, BUT it's a serial mouse on the same port as the old mouse [hence minor/major versions should be OK, since the old mouse worked...], and even small movements suffered from the above symptoms [thus discrediting Charles Hannum's second theory...] Disclaimer: I didn't look into it very much, since I was playing with other stuff, and went back to the 3-button cheapo-mouse... --rafal
