hi, have new info for you..
in vista now.....

okay in change colour section change :
menu text (to what colour you want it to be as normal default colour)
selected item (is more like a shadow for selected item text, make sure you get this colour right, otherwise it can render yr font unreadable)
selected item text (this colour is for mouseover pressed ect....)
for example if selected item text was WHITE, you would make the selected item colour a darker shade perhaps greyish........so its like a shadow, but still readable...
those 3 colours are for the start menu pop up section (and also skin photoshop drop down menu too)
start menu pop up has its own section for text and colours, ect, but it only changes when you adjust those 3 colours i just told you about.
also check out favourites menu and pop up menu, those colours can be changed in their text area in 'menu item'
okay done! truly hoped this helped!!
