real.geizterfahr: Let me guess: You're using Firefox with NoScript, Ghostery, FlashBlock and AdBlock and you told your Firefox to clear cache and cookies whenever you close it. Yes, this is a pretty safe set-up. But GOG can't stop "signing you out" as long as you're doing this ;)
i clear all things aswell on browser close /exit
but i dont mind logging in an typing the password everytime, if its safer that way.
blotunga: Actually I have the same problem in Firefox on Linux. I have no ad block stuff. Almost every time I open a new tab with GOG I randomly get signed out or something...
sometimes when i am logged in (FF is my default browser) the login button still shows.
Also when checking my replies i usally rightclick on them and open in new tab, apparently this wont refresh the state so the x number of repleis will stay there, so then i go back tot gog main page and then refresh then the notifications are gone.
Maybe its a FF thing (i have IE and chrome)but i stick with FF cause IE is bad and chrome is well not as friendly as FF is.
