SET SYSMENU OFFTo turn it back on:
SET SYSMENU TO DEFAULTTo resize the main window:
_Screen.Move(<values>) OR WITH _Screen .Top = value .Left = value .Height = value .Width = value ENDWITHBut your form will only show in the client area of the main window unless you set it to ShowWindow = 2 - As Top Level Form. A more appropriate option is to set the form's ShowWindow to 2 and in your config.fpw file put:
SCREEN=OFFSo the main VFP window won't show at all. Then, you won't have to worry about the menu either.
