two users sharing programs on one computer

Hi

new to Vista.. I can handle this problem in W95 on up, but I can't seem to figure out how in Vista.
---- we have two users on the one computer. I want the other user to have access to a program shown in my start menu but not in theirs. (FWIW - All MS programs that loaded on one user's "side" are shown on both user's start menus, but some other programs are not. I am the admin "user 1")
Using Windows Explorer, I found three start menu/program list files - user 1, user 2, and all. I went to user 1 start/program file to copy and paste the program link, but the "user 1" and the "all" start menus do not show the program that I want user 2 to be able to access (and it is not shown in user 2 start or program files, either- but it is on user 1 menu). And I cannot find anything about sharing or linking programs in the help menus.

So.. how does one normally share a program between start menus in Vista? And if it is not in the "program" list or the "start" file lists to show in the start menu, where is it?

Thanks for any help
