Ok, with MT 2.63 the first time I log in for the day and post an entry, edit a template or whatever and save it, MT dumps me back to the log in screen as if I had been logged out. If I log in again, my changes were saved, but I have to go back to the article and publish it again or rebuild template changes. After that I can save and publish normally and no longer get dumped back to the log in screen.
Anyone else had this problem?
I've had this problem with Mozilla 1.2.1, 1.3 and 1.4a as well as Opera 6.11 (all under Linux).
