ive had this probelm for several months, ive tried everything i can think of and nothign is working.

one of my drop menu items will not change width, regardless of what i do to css.

from what i can tell the rule that is supposed to alter this is
#access ul ul li {

i have changed this rule to as low as 50px, both in the child theme css and the parent theme css and yet every time i reload and check the page in firebug (or similar) the rule remains unchanged.
but when you look at the css files the changes are there.

can someone PLEASe help me figure out what the F is going on?
