I havent had any had any javascript errors, but I did notice a curious issue when changing alt tags (or actually changing anything).
This could be a Dreamweaver thing, and nothing you can fix, but it was annoying none the less.
When I changed any field (I was changing all alt tags) if I typed in a new alt tag, and then clicked the scroll bar to scroll down to the next image, what I typed dissapeared or reverted to its original state. However, if I clicked inside another text field there was a quick refresh of the preview pane, and the change stayed.
Is there anything you guys can do about that. I was at first stumped why only every other one of the alt tags I changed actually changed until I dug a little deeper, and noticed that on every other one I clicked inside the next box after entering the alt tag (that one stayed) and every other one, I clicked the scroll bar after entering the new alt tag, and that one did not stick.
