Default Templates for Novice Interface
Here is a little nuisance I came across recently:
When changing the templates that the novice interface uses, it was a little tricky. It turns out that the Novice Interface selects the first alphabetical template.
I had thought it would have used the Default Templates under Tools -> Options -> Default Templates, but I was mistaken.
So if your templates are stored in: C:\ProgramData\SolidWorks\SolidWorks 2011\templates, and you want a new Drawing, it will select the first alphabetical drawing template (*.drwdot) in that folder.
To verify and check where your templates are stored: Tools -> Options -> File Locations -> Document Templates
Personally I always use the Advanced interface, but to each his/her own.
