Hi Jon,

Whether your applet works in IE7 should be completely independent of
whether ImageJ's browser launcher logic can properly spawn an IE7
instance at a given URL. Those are two separate functions. Sure, the
rundll32 command will spawn an IE7 instance, but that doesn't depend
on having a Java virtual machine accessible from your IE7.

However, I tried visiting some of the Java demo applets using IE7 on XP:
   http://java.sun.com/applets/jdk/1.4/index.html
and they all work fine on my installation. Do you see the same error
when you try to run these? Or is it just for ImageJ?
