really? Same thing happens here, like every 5 mins or so, i freeze, i can wait 1h im stil frozen, i ahve to exit and open tibia again ;o know why this happens?
started happening to me when i switched from windows 7 to windows xp (although i also switched laptops entirely in that change)
how often does it happen to you? .. it seems to happen to me every few minutes if there are a good few people on my screen and not as much when it's only me + 1 other (although field runes can cause it too i think) so it might be graphical. i dunno!
edit, ok i read your post it happens every 5 mins. do you notice anything unique about what is going on when it happens? and do you use ip changer or write "host blablabla.com port 1111" in properties on desktop icon?
