Additional Cookie Problem: User Gets Suddenly Logged Out

[محروم.كوم]

The issue with cookies and staying logged in* I reported yesterday* is still a problem. Today I encountered another phenomen. Currently the timeout is set to 10 hours (to avoid beeing logged out). I opened my browser (Firefox 3.0) an saw that I was still logged in. That was okay* because I was less than 10 hours inactive. But after some klicks I was logged out (after visiting an user's profile). In another browser (Opera) I am still logged in with the same user name. This session is also running since yesterday. What's wrong with this installation? __DEFINE_LIKE_SHARE__
