Hi Tim,
Was that client using Win 2000 because I have had a couple developers report scx corruption after a crash. We have a routine that fixes the header but the file is completely trashed with no contents after this header fix. Plus we are getting the same dialog (VFP thinks it's a different version). They were using Win 2000, I don't know if that is relevent but I have fixed other scx corruptions with header damage and never seen this.
