post.php Save File box appears when posting

This has been happening to me for several weeks now and didn’t know if it was someting to do with my machine or not. I still don’t but was hoping that it would disappear after yesterday’s 2.01 upgrade, no luck.

My machine is not bogged down in the least and I can go to any of my other FF tabs with no problem but quite often, after selecting the PUBLISH button, I am stuck waiting for this one process to finish i.e. the FF tab takes up to a minute to finish the progress bar showing that it has completed whatever it was doing. Note, I can use the other open tabs to surf with no problem and they do return pages with no problem (hence I don’t thnk it is FF) and I can pretty much immediately go to my own blog and see the results that I am waiting for the PUBLISHing tab to finish.

Yes I updated FF yesterday to 1.501 but as I said, this has been going on for weeks although not with every post, it may even be just on the posts that I am making several edits to before actually PUBLISHing.

Finally, I lost all my data yesterday so I started with a brand new WP download, install, DB so that alleviates a corrupted DB on my end. Any ideas? TIA.
