Chrome is getting cranky
If you're using Chrome the theme probably stopped rendering correctly in the past day or two. Chrome has been getting a bit more pedantic about displaying things of late. Warning: will probably be poking at that in the near future so don't be too surprised if you see some updates.
That theme issue also isn't the only problem that I've had with this site and Chrome. Chrome now blocks Drupal's module auto-updater from working properly and also is making me unable to preview posts being putting them in place. I'm currently posting this in Safari and may start using this or some alternate browser more in the future.
Must confess that I'm getting more frustrated with Google and its products lately. Currently testing out Bing and DuckDuckGo as default search engines in various browsers of mine.
