RW 7.5.2 published all but one file

I deleted all files from the host then republished all files from a site with a new theme.
Everything seems to appear on line correctly.
But RW looks like it’s stuck on the last file.
What to make of this?

So I clicked cancel then publish again and it published 495 files to completion.

Looks very similar to the problem I am having with RW 7.5.2. It tells me my upload is complete but actually freezes up before closing thus leaving all changes incomplete. I sent an email to RW tech support a week ago but have yet to receive a response.
