SOLUTION:
Ok, this is a windows xp visual performance option. If you don't have xp, well, sucks to be you.
*go to control panel/system (switch to classic view if you don't see 'system')
*click the 'advanced' tab.
*click the 'settings' button under the 'performance' heading
*under the 'visual' tab, tic the box with the caption 'use drop shadows for icon labels on the desktop'. (If you are unable to change this value, select 'custom' on those little fill-in bubbles.)
