VFP5 --> VFP6? One reason to consider is a 10 - 12% improvement in procedural code speed. We made dozens of tests in August, 1998 -- found this to be true over wide range of procedural coding. Forms are a different matter; however, with the ability to simply hide a form once it has been referenced and realizing that .Show() will bring it back without the overhead of instatiation, there remains only a few hours ( days ) per form to take care of the properties that expect to be re-created on every reference.
