Running my applet inside netscape does not exhibit the same symptoms,
everything works fine. Still cannot solve problem in Explorer though; have
tried
- overwritting destroy to flush each image then call System.gc then
super.destroy
- call System.gc at start of each game
- inserting a MediaTracker to wait for all images to load before allowing
thread to run
Images certainly load more cleanly but when the third game loads the
problems start and only get resolved by opening a new browser window. I am
beginning to think I will have to open each game in new window to force the
complete clean up of resources in the JavaVM but this will be very
cumbersome.

Thanks for your suggestions BTW....Michael.
