I have also noticed that if I am replying to a post there seems to be a time limit and when I try to submit my post I am automatically logged out and asked to log back in again. This never happened before no matter how long it took to make a post. This can be quite frustrating if one is making a long, thought out reply and it is lost. I hope you can rectify this. Luckily I always copy it to note pad first before clicking "submit".
