Jeff,
I've been using phDbase with VFP6.0 for a couple of years now without major problems. The only issue I've had was with private datasessions. But I have to add that I only use phDbase with static data. WOW, I don't update tables that have phd tags.

Do you know under which circumstances you get C5 errors or are these errors happening randomly?

>We have been using PhDbase for a number of years under FoxPro 3. We are trying to convert the application that uses it to VFP6. We have the 32-bit PhDbase library and it seems to load and work, but it is not stable. It will run for awhile, but then we get a fatal error (C0000005) and FoxPro terminates. We're an NT shop. Anybody got any clues, or answers, or workarounds, or alternate products, or ???
