When posting, if you add an attachment, save your post before you click 'Post'

SMF has this annoying habit that if you post an attachment that is too big, you lose the post that you could have spent some time on (like me usually). In case you haven't come across this, I recommend you select all (Ctrl-A) and copy (Ctrl-C) so you can paste it back (Ctrl-V) if things go south.
