My next step would be to delete the Java temporary files in Control Panel > Java under the temporary Internet files section (settings button) those are XP directions, win7 may be different but will be close. I'd also delete all temp files in Internet explorer. That'll force a re-download of all the jar files for Metasys
Excellent ideas! Unfortunately those made no change to his Metasys window. It's very strange...when I double click on an item, I can see a slight shift in the window border, as if it thinks it loaded something, but there is no text visible.
