OK I threw out the two out of the three hacks I have in. The Mark All Posts read does not effect this.
It works fine, but since I do have Netscape users AND its still my choice, I changed line 897 and 900 to ¦ instead of what you had because Netscape does not know what to do with Entities over 255.
Now I go back and add those two hacks in and find the problem.
