A couple of hours ago I made a double post. Here's why. I posted a couple of photos, but after the post appeared the images were obviously too large, so I attempted to edit the post the replace the photos. I have no idea how it happened, but I then ended up with three photos. On the next attempt at editing, despite deleting the photos, I was left with the IMAGE tags for then (complete with file names) in the body of the post. I then deleted the post and tried again. This time I was more or less successful, except that there was some sort ot progress bar on the top right of my screen that was hanging. So I hit the submit button again. I then found that I had double posted. A couple of minutes ago I posted another photo (same thread) and got the same hang - progress bar showing, no other activity. So I opened another window on the forum, and found my post had indeed appeared - despite the lack of activity and failure to return in the original windowm which I've now closed. I'm using Firefox, which crashes when I attempt to post in some forums, but I've been using it all along without problems here. Except for now.
