The application that I am developing uses page frames and has a considerable number of objects on each page. It was taking quite long to load, so I used the suggestion that is given in the VFP documentation (chapter 15, Optimizing Applications) and saved the contents of each page as a class and create the object only when the page is activated (thus loading the controls dynamically). It works perfectly for almost all of the pages, but a few generate the error "Error instantiating the object" (Error 1736). I've recreated the classes, but it hasn't made a difference. Any suggestions?
