I believe it!

In fact, while rerunning my script after working in/out the Italian-changed text in the movie, I received an inexplicable “I don’t understand” error about one variable, which was called once. Impossible! After trying different things (without any success), I change one character in the name (in both places), and, inexplicably, it runs again. Worse, I change that one character back to it’s original character (in both places), and now it works when it didn’t before! Grrrrr!!

And then there’s always those testimonies of those who try to run scripts (which most people run just fine) but can’t get it to work.

There. I feel better now. I guess the next thing to check into would be memory integrity (shudder).
