It is especially a problem if you have a mixture of different versions of VFP and FPW programs -- newer runtime tends to automagically "upgrade" the resource file and make older runtimes think it is corrupt. If I'm not mistaken, unless you have RESOURCE=OFF in the config.fpw, the runtime engine opens the resource file *before* the main PRG is started.

>First line may already be too late, at least to avoid problems. Instead you need RESOURCE=OFF in your config.fpw file, which should be included in the exe. However, in your case it sounds like you have SET Resource On somewhere in your code.
