>Which version and service pack of VFP are you using?
VFP 9.1

>maybe you could try renaming your FOXUSER.* resource files.
Someone suggested a FoxUser problem earlier and I eliminated that possibility.

>If it's just one FRX that's causing trouble, maybe you could open it as a table and scan for bad characters such as CHR( 0 ).
No, it's several FRXs, and I don't think the FRX is corrupt because this FRX appears in two different applications and it misbehaves in one application and not in the other.

>You could also try running the VFPClean.app that is available for VFP7 and higher.
What does VFPClean do?
