The Logitech is three button and the MS is probably five (scroll wheels are generally buttons, even on trackballs)
The only four button trackball I can think of is the Kensington Expert mouse.Show Image(http://schwarztech.us/contentimages/reviews/kensington/expertmouse2.jpg)
CST2545-5W which is a 5 button with 2 external buttons. Which I can't find a photo of the buttons they offer.
The Microsoft computer mice are also good quality. Computer mice ar something Microsoft has a good reputation for.
Bwahaha! Made you buy a Trackball! If I couldn't put a poolball in mine I'd continue to ignore the wacky things.
I am pretty sure he cut off his ear not his ass.
I've been only using 4 button mice w/scroll wheel since the first optical mice were popular and I'm thinking of trying something new.
Logitech Trackman Wheel Optical for $23.95
Did you try removing the ball and cleaning the insides?
No, it's new and started happening after a week. Is that the normal PM required for a one week old trackman?
That's the way it generally goes, stuff gets crappier as the years roll on. I have no doubt earlier ones were made better.

I actually think it's superior to its predecessor, both in terms of ergonomics, tracking and smoothness.
