Like ijack said go with what works. Warning on Beta versions: They are a work in progress. Beta releases may often have the latest and greatest bells and whistles, but I wouldn't use them as a primary choice. They are an unfinished work, and usually have quite a few bugs left over from Alpha phase. Stick with the latest full release of any software you are using unless you have compelling reason to do otherwise.
I was using this flash player 10.1 and no problems all of sudden this 10.3 flash player appeared and now it just hangs. Do you think it is my internet speed? How do i go about getting my 10.1 player back? I tried and no success .thanks
