I am getting a "Cannot find entry point sleep in DLL" error when performing Sleep(1000). This is new, it was working yesterday. I have tried it in both VFP 8 and 9 with the same results. Yesterday I started playing with the API functions to monitor file activities in folders. These functions appear to be working (or at these I'm not getting the error with them.) The Sleep function is declared, and I have rebooted. What possibly be causing this?
