Baggy --I agee with you.
About 1 month ago, if you scrolled, down the Unread Posts and selected one to read ,then after reading hit `Back` on IE6, it deleted this Post only ,from Unread List and left the other Unread Posts for your perusal.
I know you can press Mark as Read,but it was better, as above.I presume somebody, has altered the Software, any ideas on this please ,Webmaster ? ?
