Just to make sure, try doing it after you close your browser, but before you bring it up again. Then do bring it up again after you run the netstat to make sure that it fails.

Again, my guess is that IE is not really closing the Java applet. Or, perhaps, that empegVNC never sees the applet close because it's been killed abruptly (I didn't write the applet; I just ripped it out of the WinVNC implementation). The reason that it would work with WinVNC is because WinVNC would just kill the old session arbitrarily when it got the new connection. empegVNC waits for the old connection to end. Maybe I should figure out how to change that.
