No. No code that I have tried for the title is changing anything. This leads me to believe something else is overriding it. Possibly a plug-in.
I am also changing this code in the theme header. Is it possible this code segment is also in the wordpress code?
These are my active plug-ins:
Akismet
Apture
Contact Form 7
Dashboard Post-it
Digg Digg
Google Analytics
Live Blogging
Page Links To
Really Simple CAPTCHA
Revision delete
WP-PageNavi
WP-PostViews
XPertMailer
If you see something that would cause a potential problem let me know.
