Had a really strange one I wanted to relay to the UT. Had a VFP 3.0b system running on a new PC. One form has two combo boxes. The second combo box is derived from a SQL statement based on the value of the first combo box. Well, everyting worked fine on the development PC, but the new PC had difficulty. The second combo box would not populate properly. So, I went into the code, put wait windows, used the debug window, ...etc. No luck. I rebooted the PC and everything seemed OK. Did I experience some sort of corrupt memory problem or what. I have heard about these problems, but this is my first experience with it. Very scary... Any comments are welcome! Steve
