On the other three systems I deleted Java 6 first and then installed Java 7 - TR pages now appear the same in FF 18 and MSIE 9 and 10 (one system is still XP with IS 9). However, there is still two issues with the Java in FF 18.

It's clear you HAVE to delete 6 befor einstalling 7 as I still have issues on the system I added 7 before deleting 6.

1. If the list preference is in collapsed mode the title shows but I can't get the individual post to display inb line, it will display properly if opened in a new tab.

If I change the preference to 'expanded' then the posts all display.

2. Regardless of the display options above, the links for edit, reply, flag, and favorite do NOT work - they just sit and spin. Clearly there is still an issue on how FF 18 is handling these commands.
