Staying logged in

I'm having a very difficult time staying logged in ever since I changed my password (eccie suggestion). It seems that after logging in when I try to access any new area, say a showcase, I will be taken there but not logged in. When I log in again it takes me all the way back to the home page.
This is happening on both my home computers ( Mac and PC), my iPad and iPhone. I have used both web version and mobile version with same results.
I'm getting frustrated with this awesome site.
Suggestions?
Thank you.
