I installed the prerelease 1.6 JRE. It did not touch my Java control
panel or register itself with it. So how do you trick a browser into
using it?
Just a wild guess, but it may work - only for Opera under Windows.
Opera uses the registry to find the current JRE, and uses that to run
applets. You may be able to make Opera use the new version by temporarily
changing the registry setting
HKEY_LOCAL_MACHINE/SOFTWARE/JavaSoft/Java Runtime
Environment/CurrentVersion
If there is no sub-key 1.6 you may need to make it. Just copy the 1.5 one
and change the relevant paths.
