ive got some questions..

1) is there any way make a Command button into different shapes? (like circle). if so how do you do it and what do you need?

2) i was wondering how to do a program just click a button and it opens a new window... example you logged in(MSN or yahoo) and it opens a new window that let you see your friends. from the log in part into the chatting part(do you get me?) lol.

thanks in advance
