Choosing menus from the keyboard

[Ron]

Greetings

Are there any reasons, obvious or special to RR, that command key
equivalents do not activate the menu?

The application has a mainstack that is a palette, other wds include palette
and regular editable wds. When the menu is chosen from the menubar, it works
as expected but the cmdkey equivalent from the keyboard does not do
anything. Well, sometimes the menu on the menubar flashes but nothing
happens. Even simple menuitem like "paste" won't work.

Thanks
Ron
