I have spent literally hours on this!
My problem is that when I upload files - htnl or otherwise - i cannot obtain, any previews.
I press either of the Preview buttons, an IE browser opens but is empty, although "source" indicates that the file/s is/are present.
When you then go back to BV, no files show up so I could never build a web page!
Could my use of Interne Explorer 8 have any bearing on this - for me at least - very major problem.
