>The problem I was getting was that I had to recompile the class in 5.0 if I used it in 6.0 - this was getting a bit tedious. I am now keeping a separate set of libs for 5 and 6 and life is a little easier. I only *support* 5.0 and all new development is done in 6.0 so I have had no problems with updating 5.0 libs and having to maintain two sets of libs.

FWIW, you should also always recompile VFP5 classes in 6.0. I've had some
really hideous problems with that which were related to calls to things
like the new file functions in VFP. In 6 it wouldn't find the new functions
in the language, but also not work with the ones compiled into the classes.
