>VFP does a static read of certain environmental registry values into system variables on startup - you may need to force a refresh. This a is a SWAG, but you might try issuing a SYS(3056) to force a re-read of environmental veriable settings from the registry; I haven't tried it.

Ed,

I thought of this too, but my experience has been that it only reads the settings pertaining to VFP itself, and not the system. Further, the documentation seems to back this up, referring to the registry settings as "its" (VFP's).
