I like the case I have but it lets the darn buttons that turn off the ringer get pushed.

Ah, the Internet.

I discovered that you can press the CLR key and then press the * key and it locks the keyboard  AND those side buttons.  It receives calls and I can answer them.  If I need to make a call I just have to press CLR and * again and it unlocks the keyboard as well as the side buttons.

Problem solved. 

Thank you for the replies.  Posting here got me to looking for a possible solution.  I really like Google and the Internet.  (and the people on here)
