What's wrong with vBulletin? Can't edit posts or see preview text.

[BobBridges]

I've been away a while, and returned for a visit. I notice two apparently related problems in vBulletin (that's the software, apparently, that powers this forum):

1) When I try to preview my reply before I make it final, I can see the preview but the text box where I can make changes is empty. I have to back up to the previous page to make proofreading changes.

2) Similarly, when I post a comment and then try to Edit it, I can't; it opens up the box for me to change my remarks but it's empty, my text isn't there.

Is this something new? Is it happening only to me? Has it been reported? Is it being worked on?
