Applet not running: Stanford Engineering Everywhere Hangman

I've written working on a java applet, which seems to be opening sun.applet.AppletViewer when it is running. I'm using the acm libraries for the Stanford Engineering Everywhere Hangman assignment. The problem I'm having doesn't seem to be with the code, unless I've not done some implementation I should've. Basicly Applet Viewer is hanging just saying "starting applet..." and the program isn't running. I've not encountered this problem before, so I figured I'ld ask here in case anyone has encountered a problem like this before. I guess it might be the default exception case that is getting thrown, but I'm not getting an error message so I doubt it.

I think the code should be working, but I'll post it in case there is something obvious I've left out at this point. I'm not quite finished with the assignment, but I'm fairly confident it would work if I wasn't having this problem.

I've not yet finished with the other file, but I don't thing that should be an issue of concern until I've got the applet thing sorted out.

Nevermind. I figured out the problem. I should've been doing this in the run method.

guess = readLine("Your guess: ");

That was a really stupid mistake on my part. lol. I thought I'ld already tried that.
