Just a thought - have you discovered how to use the trackpoint 
sensitivity settings?  I find that it is much nicer to use when the 
sensitivity is set to 255 (default=128).

If you haven't, try it. You may decide you never want an external mouse 
again!

Let me guess - in WinXP, you don't have a working Middle-click on the 
external mouse [press the scroll-wheel] ?

The mouse button mappings can get a bit weird sometimes! xev will show 
you what is actually happening.
