Being logged out while typing a reply

[Stephanieinar]

It seems that whenever I am typing a reply that takes more than a minute or two, when I click the reply button to post I receive a message about trying to access a page I am not allowed access to. (or something similar). I end ut having to copy the message & log back in again. It's rather annoying as some replies take more than a few words. I could understand it if I had left the computer to do other things but not while I have been actively typing.

Am I doing something wrong or is it just a weird glitch. Is there anything I can do on my end to help prevent this from happening?

Thanks.
