I've had it happen a few times now that when I've been in the middle of replies, where my 'session' has timed out even though I've stayed logged into the site permanently. This is really aggravating, because I'll type of a nice long post, and hit submit. Then, it gives me an error, but doesn't save my text in the form, so when I go back to the previous page, it's all lost.
What's going on with this?
