<p align=left>On Vista SP1 x86 that code gives me exception 299 randomly.  However, after the exception is thrown if I run the program again it works fine.  But then if I wait a few minutes it throws exception 299 again.  I really dont want to implement API calls to replicate this functionality.  Any ideas?

<p align=left>(btw, references to ANY property of the Process throws exceptions.  Also, its not limited to cmd.exe its just used to illustrate the point.)

<p align=left>I tried getting around it by catching the exception and retrying whenever the exception is thrown, but that results in an infinite loop.
