I also have a logitech optical, but mine is cordless maybe that's the problem?
Small update: you're one line macro does actually work!
Next question is why doesn't it run in a macro which opens firefox first, starts up a website and then has to scroll.......
Small update 2: This is strange, with the following lines:
mouse move screen: xx,yy
mouse wheel 3 clicks backward
it does scroll, no problem at all!
but with the exta line:
Web site: http://whateverwebsiteIchoose
mouse move screen: xx,yy
mouse wheel 3 clicks backward
it doesn't work anymore!
how about that.........
