Microsoft Security Patch MS04-024 causing problems with System.Diagnostics.Process

[Brad]

I just recently applied the security patch MS04-024 and now in a
program that uses System.Diagnostics.Process when I start the process
it prompts for a response in a file download dialog box. This is a
program that runs on a scheduler and is not watched by a user. Is
anyone else having this problem? Does anyone know how to get around
the problem? Here is what I am doing.

Dim app As New System.Diagnostics.Process

With app.StartInfo
.WorkingDirectory = "h:\"
.FileName = "pkzipc"
.Arguments = "-add -move -store -over=all -before=deleteme.zip
C:\files\*.*"
.WindowStyle = ProcessWindowStyle.Normal
End With

app.Start()
While app.HasExited = False
SleepEx(600, 1) 'wait 1 minute for it to finish
End While
Before it would run ok now it prompts a file download box.

Any help would be greatly appreciated.
Thanks,
Brad S.
