Hi, we are working VFP9 sp1 with VSS2005 and this version is more flexible for interactive application, and this have the utility to reapre the database of vss when vfp is crash.
VFP9 have many changes for work in goups focussed to vss2005 (not vss6c recomended)
When I work vfp9 with vss6.0c we have many problems, problems with database of vss and problemas with ckout and chking.

Best regards
