I just updated Java again to 7u10, this time making sure to do the installs from the administrator account and making sure to install the 32bit version last, but I'm back to LW acting as if it was the software that was freshly installed, asking all the configuration questions it asks when first run and ignoring my existing config folders. Last time, that problem magically disappeared once I got the Java install right, so I never dug into what could be causing it, but this time the problem won't go away.
