PROBLEM not able to switch between page templates

Yeah they are the same some thing is overriding your install, it's not the theme afaik , it works for me.
A theme that is not active is breaking your site? Not sure how that's possible as it should not even be included unless it's active. Now there is a file check that falls back to template.php so if our file exists check failed it could do this.
