Thanks. At least I know I wasn't doing something obviously wrong and others probably have the same problem. appletviewer has been working well. I guess if I need to load it in a browser again I'll tell it not to keep browsing history. The problem with going Tools > Internet Options > Browsing History > Delete every time is that it's probably about as inconvenient as starting a new browser. I'm pretty sure I was having to delete the .class file the day I made the post. Starting a new browser alone didn't do anything. But it doesn't seem to be doing that anymore so I don't know what that was about.
