Ok, I had this same problem, with a twist. (FPW 2.6)
Our Fox source files are on a Novell server, my workstation is an IBM Intellistation dual processor running Windows 2000. For some reason, this PC seems to corrupt the .SCX files (the wysiwyg screen forms), resulting in the "memo" error from GENSCRN. This same error occured when simply attempting to open/edit the screen form.
The solution was to start over on a Win95 PC, ERASE all the .SCX files from the project folder, then build the project with the "rebuild ALL" option on (apparently it reverse-engineers the .SCX from the .SPR). We also discovered issues with drive mappings and the project having "hard coded" drive designations - the project must "think" it is in the drive and folder it originally compiled in. Otherwise, we continued to get the "memo" error.
BTW - If running the code above (which I did) ERASES your .SCX files, you most likely have this same issue. (yes, I know there is NO LOGICAL REASON why this should happen, but I repeated the experiement several times with identical results). This cost me 2 day's work to figure out. BTW, common sense here - save a copy of ANYTHING before you delete it.
Another solution is to regenerate your .SCX files from the compiled source code using a decompiler like REFOX. The .SCX are not automatically regenerated, but there is a separate FP app distributed with REFOX that can get the job done. You have to read all the documenation THOROUGHLY to find out about it - check the .hlp file, I found something in the last paragraph on the topic that proved to be the key. REFOX 8.0 can be obtained for about $400.
