>How do you set it up so that if the user splits the grid or moves columns in a paricular order it stays? Each time a new selection is made from the 'main' form, the grid goes back to the way it was originally.

You would have to set up a table of preferences where you could store the previous settings. Then in the INIT of the form scan through that table and set the properties. This table would need the form name, user name, objectname, property, setting. ObjectName and Property could be combined into one.
