>Flexing my muscles in VFP6.0 (yet again) I have built an app using the application builder. So far not too bad. Added a "Data Buttons" class to one of the forms (Yes I did sub-class it). Performs perfectly under VFP. However trying to run it as a standalone .exe, without VFP interpreter, some of the button face images diasappear. WHY??

You probvably either failed to include the graphic images in your exzecutable, or if you didn't explicitly include them, put the individual graphics files where the VFP application could find them. If you include them in your project, don't reference them with an explicit path in code.
