If you create a new XML to HTML Stylesheet using Stylus Studio Version 4.6 Build 103s on a Windows 2000 SP3 machine and add to the XSLT Source, every time you go to the WYSIWYG tab, the editor will add a 1 after the element. Original XSLT text: Went to the WYSIWYG tab and back to the XSLT Source tab. New XSLT text: 1 Went to the WYSIWYG tab again and then back to the XSLT Source tab. New XSLT text: 11 As you can see, every time I go to the WYSIWYG tab, an additional "1" is added after the element.
