I'm a teacher; not a programmer. I dabble a little with stuff I oughtta leave to professionals. That means I make simple mistakes. I "know" I'm missing the obvious in this external .js file I've written. What's causing it to hangup? (I know it goes on one line.) document.write(" "); MSIE delivers a cryptic error message (which I don't understand.) Bypassing that, the pop-up window does not open in correct size.
