This happens with me. I would believe it is just your session timing out due to no activity for a period of time. Typing is not really activity in it's mind. As mentioned before the easiest way to remedy this is the copy and past function, although you do not need to do it prior to hitting submit every time. Only if it gives you the error, at which point you can hit the "back" key on your browser which will take you back to the text entry with the text still in tact. From there select all the text, do a copy (either right click and copy, or from the edit menu at the top), hit back again to take back to the thread, or possibly a login screen, if it is the login screen, if it is the lock in screen just hit back again, hit post reply, paste, and then submit.

Not sure what could be done by Sling, unless he can change the timeout time, however in doing so he may run into bandwidth issues for people like me who never log out knowing the system will do it for me.

But using this procedure should make it pretty simple and less frustrating.
