A directory name with spaces in it?

>Hi,
>
>I have sucessfully launched an external windows program from a menu button in a vfp application for years on many types of computers running many different OS's and SP's. Last week I install the same vfp app on a dell optiplex 780 running windows XP pro. When I hit the menu button to run the external windows program the external program opens and then closes after 2 seconds.

>I have attempted to launch the external windows program using:
>1)run /n
>2)run
>3)ShellExecute
>4)WinExec
>5)CreateProcess
>
>All gave the exact same response. Namely: the external windows program opens for a moment and then closes. At the same location, (all serviced from same firewall with virus and spyware shut off) I installed the program and external windows program on several different computers. It is only one computer that is experiencing the problem.
>
>I then substituted notepad.exe for the external windows program. THAT WORKED FINE on all computers including the one in question.
>
>I then wrote a 1 form vfp program and compiled into an exe. That program was able to run the external windows program just fine on all computers.
>
>So the problem is specific to my initial vfp app installed on a particular computer. Everywhere else it is installed it operates fine.
>
>I even had my vfp app run a vfp app compiled into a dll and a vfp app compiled into an exe which launched the external windows program and that did not work either. I also had my app run a batch file that runs the external windows program and that did not work either.
>Today I created a .net windows form app that launched the external windows program just fine. BUT... when I had my vfp app launch the .net app the same symptoms occured.

>Any thoughts? What might be missing from this computer. What might be running on this computer.
