menu icons not working

[attachment]C:fakepathmenu_icons.css[/attachment]
I have the latest Joomla 1.5 version as 1.0.10 and have found a problem using some of the sports menu items. Soccer, Volleyball and a few others do not show up, you get the joomla icon instead.
After figuring out how they are displayed by moving an offset in the icons.png file I noticed that there was an inconsistency in the way offsets were used.
In the file menu_icons.css around lines 204 the incremental offset remains at 516px which is the one used for the Joomla icon.
If you go in and add 80px to continue the series of ascending offsets all the icons will be displayed correctly.
My version of the file is attaced.
Hope this helps someone.
