[UK-CONTEST] Error Message

[G3SJJ]

Need some help again with my computer, please. On certain applications the
machine crashes with one of two error messages: An exception has occurred at
(1st msg) 0028:E819F17A (or 2nd msg) 0028:000000A in VxD---. This was called
from 0028: C1C2DB50 in VxD voltrack (04) + 00000430.

I've looked this up on the web but can't find the exact problem. Any
suggestions, please?  Chris G3SJJ
