I have an Excel file with 6 worksheets and some simple styling of the fonts. I use "Save As" html type, and select Entire Workbook. When I view the html page on my local machine (Windows 7 64bit, IE 11), it all looks fine.
When I copy the files (filename.htm & subdirectory) to our Win2008 Web Server and view in IE11 browser, only the first worksheet looks correct. The other 5 worksheets have wrong font size and strength. Sheet1-OK.jpg Sheet2-wrong.jpg

I have done this many times in the past without problem. The only thing changed is a new desktop computer (Win 7 64 bit - same as old one) with Office 2013 instead of Office 2010.
