<< They seem to have lost some steam in keeping up with VFP 5.0, judging from the reduced level of promotion I've seen lately. This is only a guess, since I have very little direct experience with any of them.
I would think that any framework that got its start before VFP 3.0b would be due for a serious overhaul. >>

They have lost steam for two reasons. First, FoxPro lost steam but is definitely on the rebound in a big way. Second, the software gurus of those products had to start from scratch just like the rest of us to figure out what all this new stuff was in "Visual" FoxPro. As those of us who worked (and still do) extensively with FP2.x DOS and Windows know, Visual FoxPro of any version ain't your father's Oldsmobile.

I can speak directly to Visual FoxExpress in that it is still in beta (but near done) because they have given it a complete overhaul. It is not a rehash of their version for FP2.x. This has taken far more time than they ever anticipated, but they are determined to do it right. And, in the middle of their rewrite for VFP3, VFP5 was released. That added a few inconsistencies that had to be addressed in their rewrite. If you'll look at their web page in the beta section (yes, you can get that far), you'll see they have two builds of their product: 1 for VFP3.0b and one for VFP5. Also, they even have a FoxExpress 2.7 also near done for users of FP2.x.

Anyhow, I just wanted to add my $.02 as to why these app gens seemingly have lost steam.
