My Programming Bible (which I should have read in the first place) says I must call FrmRemoveObject to delete these dynamically created controls when closing the form. Why? Doesn't deleting the form free all this allocated memory? Even more so if the form structure gets expanded in memory when adding controls. -- Luc Le Blanc -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
