Not sure if this is just my setup, or a bug/feature of Araneae...
Often when I open a document to edit (either by 'Open With' in Windows or 'View Source' in IE), the document type at the bottom of the Araneae window shows something other than what the document is, and this affects the highlighting.
For example, I open my website locally (which is XHTML 1.0 Strict) and the highlighting is for HTML pages. Or CSS pages will appear as Standard documents with no highlighting.
Is this a bug, or just my setup?
