Thanks very much for that, Tracy.

I didn't see much way around keeping/changing multiple versions of the code but was hopeful that maybe someone had a "magic bullet" that allowed otherwise.

We should have the luxury of insisting that our users stay "current", not necessarily with bug fix 'releases' but with "version" (new features added) releases. That should make the burden considerably less than yours. I bet you can't wait for the end of summer.

cheers

>In the longrun, all users will be upgraded to the final VFP8 (soon to be VFP9) version. A large number already are. We instituted the requirement to run the latest version for the user to have Windows 2000 or Windows XP. All the 'hot' new features are only added to that version to entice our users to upgrade their hardware or else they never will. In the meantime, we actually have two versions WITHIN each of those versions which works just as Craig and Scott described. We have a 'live' version and the version in development or 'upcoming' or 'next' version. Only critical bugs are fixed in the 'live' version and beta updates provided for our users to download and install when necessary. All features are added to the 'next' version. That means that critical bug fixes are implemented in BOTH versions. There have actually been times when a fix has had to be implemented in 8 copies of our app. That ocurred when the homeland security rules took effect and the new requirements had to
> be implemented for all financial institutions. Luckily that is the only time that I recall a fix that was relatively 'major' and not a minor fix.

>>How do those of you who sell your applications on either a subscription basis or with an annual maintenance and support agreement post-licensing handle the fixing/distribution of customer-reported bugs AND the development of enhancement to the product?
