I am testing my SV in different browsers... running IE locally some of my thumbs come up missing.  When I publish to the net and use IE as my browser, the thumbs are there and everything seems to be functioning properly.  SV works fine in safari, ff, and netscape... no issues.  Should I be worrying about the fact that SV's thumbs come up missing when I test locally on IE or, being that the final output will be on the new, should I be thankful that it works when published and move on?
