Over the last few weeks I've been having an issue with the reply box. At first I thought it was my pc, but I've had this problem on 3 different computers.
What happens (and its frequent but random) is that I will lose the ability to start a new line for no apparent reason. Basically, the enter button ceases to function. Refreshing the page fixes it (momentarily), but it's extremely annoying if I'm trying to write a long or spaced-out post.
Again, it may just be me. But consider looking into it. I think it'd be a strange coincidence if it were just my 3 computers and nobody else.
