This same Applet works just fine in MS IE but totally fails in Firefox.
Running the following code in Microsoft IE, it runs fine; in Firefox, it does not. The code is 'straight vanilla' code and shouldn't cause any hiccups, but it does. I've also included the Java Applet code for evaluation; it too is 'straight vanilla' code. Anyone one have any ideas as to why it runs in IE and not Firefox?
