>If a menu brings up a sub window, is there any way to have the menu return to the selection it was at when the sub window closes? For instance, File-->New (do work in pop up window), then when the pop up window closes, the File menu is back open with New highlighted. Thanks for any help

You can try stuffing the keyboard with the shortcut keys needed to open the menu:

KEYBOARD '{ALT+F}'
KEYBOARD '{N}'
