browser: mozille 11, opera 9, ie5 (same bug on all)
example profile: http://hwbot.org/user/massman/#My_Submissions
if I select Motherboards then ReferenceClock (default) field is empty as if PJ had no submissions
same for Videocards-3DMark01, Memory-Maxxmem and Processor-SuperPI
but if you select Videocards-3DMark03 and then 3DMark01 - then submissions are shown
