AOL for Mac OSX Browser Problems as well as can't find the "send" button in AOL Desktop for Mac

I have an iMac w/Intel chip running Mac OS X Ver 10.5.8.  I use AOL for Mac OS X ver 10.3.7.  I have significant probs with it's browser.  Many sites cause AOL to quit when I access them, so I use Safari. Other sites don't even load or are very slow. I can't seem to to update this browser to accept Java.  

So, I tried to use AOL Desktop for Mac Ver 1.2.1.  It allows me to receive e-mail and even use IMs and does not have the browser problems that the other AOL has.  However, If I write an e-Mail or try to reply to e-mail, I cant find a "Send" button??!!

Thanks, Louie
