i had the same problem did all what you mentioned above but nothing solve it .. this is what i did to solve mine
right click GnoMenu button -->Properties -->Icon Selection --> change WIN7 "For me i chose BW "
now it's working fine.. i hope it works with you ..
i hope also that you confirm here if it works or not to help other ppl
i hope form developers of GnoMenu to fix the WIN7 Icon Selection and make it works
Thanks in Advance
