Is there a space in the file name?

>When I run a program from an icon on my desktop, VFP opens and a message box appears saying, "File '.prg' does not exist.". When I click on "OK", the program proceeds to run to a successful conclusion. The program I run does not include running another program internally, nor is there any reference in the program to any other program. I have looked through the "Options" menu in VFP to see if there is something that looks for some program when VFP opens, but to no avail. So far, that little error causes me to have to be at my computer when I run the program, which is very inconvenient. By the way, I'm running VFP 6.0. Any ideas? Any help would be greatly appreciated.
