@C - I think it may be your machine. I just went over and everything works fine there for me.
Try closing and reopening your browser and try again.
Sometimes (very rarely) the forum gets confused about a posting, times out on the upload, and then won't let you post because it's still in limbo on the screen refresh. If that's the case, just copy what you wanted to post, go back to the forum home, then return to the topic, paste your comment back in and post it again.
Before starting this topic I: closed browser, ran disk cleanup and deleted cookies, ran quick virus and mal scans. (Nothing)
Just now tried again but no change.
The plot thickens... tried another outdated
topic of mine 'ZOOM setting reminder', in General Software Discussions, and it works fine.
Maybe this is Area Specific@DC... for only me? I dislike being the center of attention anywhere.
This is frustrating at best.
-------------BTW maybe one of the admins can/will move this thread to Posting 101, where it really should be, and delete this sentence. =)
