Hello,

When I use never versions of jQuery than the one in the book (1.2.6), I get the following error in IE and the scripts don't work.

"Object Expected"

If I switch to a newer version of jQuery in the examples from the book, the same thing happens. This happens with versions 1.3.x through 1.5.x.

Does anyone know what is causing this or how to fix it?

For some reason, my browser's security settings were messed up. Fixing them resolved the problem.
