I'm sorry if this isn't the appropriate please to post this but I wasn't sure where it should go...

I was wondering if anyone could tell me why when I log into my yahoo messenger and then go to click on anything it automatically logs me out. Even if I go to paste something in a messenger window, as soon as I right click on the box it logs me out. Any idea what might be causing this problem. I know I'm not the only one experiencing this because two other people I know are having the same problems. Is this a messenger glitch? It didn't happen until I downloaded the new version of messenger but now even when I try and go back to the old version it still gives me the same problem. Any suggestions would be much appreciated.
