A client is moving a FPW 2.5b app from Windows 3.1 to Windows 98. The app refuses to start, indicating an I/O operation error. At first, I thought the problem was related to the Divide by Zero problem experienced on fast, modern computers, so I had the client patch FOXW250B.ESL with DZPatch. Unfortunately, this made no difference. Does anyone have an idea what the problem might be?
