Hi Yakup,

First, I was unable to get your applet loaded in either IE or Netscape
on my machine.  You should run your HTML applet code through Sun's
HTMLConverter program (downloadable from their site) to ensure your
applet works in both IE and Netscape.  I have set up an applet at
http://www.ssec.wisc.edu/~curtis/applet as an example.

However, my example applet also suffers from the problem that you have
described, where upon being run a second time, no data is visible
within the VisAD display.

Unfortunately, I have not found a solution to this problem.  I noticed
the following things while experimenting:

1) If you go to the Java Plug-in Console in IE, and press 'X' to clear
   the class loader cache, then reload the applet, it works again.

2) If you refresh the applet web page a few times, after a few tries
   it will display properly again.

Based on the above, my guess is that the problem stems from the Java
Plug-in class loader, although I have no idea if any work-arounds are
possible.

Sorry I can't be of more help.
