This is not actually a problem for Mathematica. It is rather the other way
round, that running Mathematica is fatal to POINTER.EXE. If you have 
POINTER.EXE running when you launch Mathematica you will get a message such
as this:

                  Application Error
       GROWSTUB caused a General Protection Fault in
           module GDI.EXE at 0001:4521

Mathematica will run with no problems. You can leave POINTER.EXE in place
if you don't mind getting this warning every time you run Mathematica.
However since all it does is change the size of the cursor it should be
pretty easy to live without.
