Converted 2.6 app (which runs very well in 2.6) has several screens that work well together. Have main screen with menu options that bring up more information (more screens) regarding a product. If a change is made on one of the 'child' screens have a variable 'editing=.t.' then when the user leaves that screen, the main screen disables most of the command buttons except the save and cancel. Since converting to Visual 5.0, if a change is made, upon returning to the main screen, it doesn't see that editing = .t. and does not disable the buttons or offer the enabled 'save' and 'cancel' buttons.
