I got this message from a user:

The VFP EXE won’t open for me.  
Is there a problem with the system/program?  
What can I do to fix it?

I took a look at the computer she was using, which is a Win2003 Server dedicated terminal server machine used by several users via Remote Desktop Connection (and this is how she was using it). So I tried to run the VFP EXE as usual. Would not run. Reported "invalid vfp8r.dll" . Here's what's odd: The _valid_ vfp8r.dll was still where it was supposed to be in "C:\Program Files\Common Files\Microsoft Shared\VFP". However, within the VFP EXE's home folder was a corrupt DLL file also named vfp8r.dll, about half the size of the actual DLL. Its creation date was about 3 days ago. Since the windows loader always first looks in startup dir of an EXE to find support DLL's, it errored out on startup. I have _no_idea_ how that DLL got there. I renamed it to vfp8rbad.dll and the EXE then found its correct DLL in the Microsoft Shared area and now runs fine again.

Has anybody else had this kind of thing happen? It seems at first glance that somebody intentionally tried to hack the app.

Thanks very much.
