That is a very specific exception - what are you trying to do with a Thread when it occurs? Apologies to all for the multiple posts - I wasn't aware of how long it would take for a message to make it to the list. There's a thread in the applet code which handles display changes; specifically, there's an applet called DisplayController. Upon pressing the applet's button, I get this exception, and it pretty much dies in the event handling code when it tries to create the thread. I'm not even sure if this is specifically Tomcat or Java which is not allowing me to create a thread...
