I think someone already mentionned this but check out the SET SKIP OF command in HELP. When you go into your edit method you can issue a
SET SKIP OF BAR NEW OF FILE .F.
whereFILE is the name of the drop down menu where edit is found and NEWt is the name of the edit bar option. Then when you exit the edit routine, issue
SET SKIP OF BAR NEW OF FILE .T.

Another option is available if, for example, you have a toolbar with a NEW option on it. You can then set the SKIP FOR portion of the menu bar for new to the ENABLED status of the new buuton on the tool bar so that when you disable the toolbar button, the NEW menu option is automatically disabled as well.
