Okay, enough back-and-forth bickering. It's not
that important an issue.

I'm not sure why you would intentionally misinterpret the rules in such a broken fashion (Resilient Shere, in particular, becomes an incredibly broken spell with your houserule).
Err... it's not a house rule. As people have already explained, the rules are exquisitely clear on this issue. You simply can't cast spells from behind a closed window. In this case, the precedent is unambiguous and easy to understand; except for gaze spells, there is effectively no difference between a see-through window, a see-through wall, and a solid wall.
And just so we're clear, I playtested the 3e rules starting a year and a half before they came out. I run a high level campaign and play in both a low-level and a mid-level game; between these and RPGA judging, I'd estimate I've played in well over 200 3e games. And in none of these - not one - did it "break" the game. It seems to be a good rule, and it works well. Doing it your way is fine - but it's a house rule.
Incidentally, if someone was hiding in a phone booth - assuming such things existed in my game - I imagine someone would use a lightning bolt to shatter the glass before following it up with a hold person.
Ratama, I know you're new here, but you might want to lead off with a little less insulting manner - even when you totally think people are wrong. I think it made a bad impression on folks, which twisted the course of this thread. In any event, welcome.
