I have an xslt-file with xsl-Tags and html-Tags and if I open it with Dreamweaver MX all html-tags are in Uppercase. When I open the file with an Editor like Ultra-Edit the tags are in small letters.

If I convert with the editor from UTF8 to ASCII having the file still opened in Dreamweaver, Dreamweaver realize that the file has changed and after refreshing it, shows the tags in lowercase. But if I close it and open it again, the tags are uppercase again.

Any explanations or hints where there are options to change this behavior?
Thanks for help
