Using windows XP right now I find I am still logged in when I revisit after 24 hours which is fine. MFF as a browser. But top right I see the 'not logged in' or whatever it says, but my name over on teh left is 'welcome Mozzytheboy.' This is curious because I can still post despite the message top right? Any thoughts?
Also, down the bottom on the left is a live link to country origin (change), I click the change and hit UK and lo and behold it still states USA?
The "Sign in" button at top right is for logging into the Adobe Store. And in spite of what it says here
the "Change" button next to the United States signs produces no perdurable effects. More correctly, I should say it did not up to the last time I tried, but I am not willing and do not have the time to do any tests now, so I'll take your word for this.
