If IE9 Developer tools are running it loads fine.
If I load IE9, load the developer tools (F12) then kill the developer tools it still loads fine.
If developer tools are running then sometimes (but not always) the first message in the console is:
HTML1113: Document mode restart from Quirks to IE9 Standards
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml">
If I change doctype to and remove the xmlns nothing changes.
I'm stumped. Any suggestions appreciated.
