refuses to open file

[rbtwms at digitalpath.net]

Let's start over it has nothing to due with the file.  It's the file name
thats the problem.  I wote a short test program to demenstrate the problem.
It shows that if the file name has a path it causes the exception. i.e:

(prompt)dir
 Volume in drive C is OS
 Volume Serial Number is E221-AB60

 Directory of c:\d\projects\equipment
