Anti-aliasing and radar gauge for FS2004

Hi all,2 questions. 1. I recently installed FS2004 I changed the options for the display and checked the antialiasing box. Much improved graphics but in cockpit view the panel of my aircraft disappear. I using anti-alising in FS2002 and do not experience this problem. Anything I can do apart for unselecting this option?2. where can I find a freeware AI radar for my aircraft that works in FS2004? I use AIMap and Eric M really good radar in FS2002.Thanks,Andrew
