Just a note to self here.
Tonight I noticed some problems with Syntax Highlighter Evolved, the plugin I was using for code and XML snippets, etc.
I was trying to load a page with an XML snippet and my browser was reporting that it couldn't find the XML brush. Reinstalling the plugin probably would have fixed it but, all the same, I switched to Syntax Highlighter Compress which, true to its claims, does seem to work faster than other syntax highlighters I've tried.
