(...) Maybe we can get to the bottom of this one. Try the debugging command line switch -g and see what it prints out when you do a mouse spin.

(...) I like the idea of absolute based on the zoom. So, at 100% zoom, 100 pixels will rotate it x degrees. At 50% zoom, 100 pixels will rotate it by x/2 degrees. Just my idea. I don't know if it would actually be nicer or not. James (22 years ago, 11-Jun-02, to lugnet.cad.dev.mac)
