>That isn't the point though. The point is that a security fix may be needed and it may disable some things that keep VFP apps from running. (Kinda like one of the Win2000 Server patches a while back that gave us trouble with remote object instantiation). If something like that happens, then admins probably wouldn't be happy for large IT departments to find a work around for a security fix (security fixes tend to have the side effect that they don't have work arounds < s >).

Yes, you're right. There can be breaking changes like that even in XP once the support expires. Fortunately VFP is quite simple in general, so most security changes should not affect it. Unfortunately, security changes are totally weird so the ony we can expect is the unexpected. < BG >
