Groups and Messenger Conflict for Login?

I have one Yahoo account with two profiles. I use one profile for Groups/Yahoo and the other for Messenger. What I mean is that if I go to the Yahoo main page and Sign In, it is with my primary login. When I login to Messenger, I use the secondary profile.

So, suppose I am logged in under the primary account to Yahoo, and I logout/login to Messenger using the secondary account, I have to re-login to Yahoo again. Since I am on a laptop, basically everytime I power down the laptop, Yahoo forgets me, since Messenger logs out/logs in. So, I never get the advantage of the stay logged in for 2 weeks. Now, it seems to me that this was not like this when I was one an older version of Messegner. Drives me nuts.

Anyone have this problem and fixed it???????????
