Hello CABAL,

Looking at your error-messages it seems to me that you have a lot of windows open without any error handling programmed (except for the default eventhandling of the window-windgets). When you open two windows in the order 1 2 and you close them in the order 1 2 you can get an error.
Part of these problems can be solved by using DIALOG-WINDOWS
(DEFINE {&WINDOW} AS DIALOG.) That way you HAVE to close the windows you just opened before being able to move on to the next window. If this is not an option you will have to write your own event-handling. A HINT:
With the IF VALID HANDLE phrase you can ask PROGRESS whether a windows is open or not.
You can always ask for more specific questions once you're on your way wrinting the code.

Succes!
