copy and paste from wordpress page

Hello all-  My site is live thanks to a lot  of late night hours and some help from several of you .  Here is the URL

http://www.tandenllc.com

Now the question.... Somehow my pages are coded that my users cannot right click copy to select content from the site. I have searched and am unable to find out why?

I have searched all the dashboard options w/o success and several sites.  Is this a java issue ?

Thanks

Mike
