ok..when i put my muse over a icon the writing comes out big and bold!!

im sure its not supposed to be like that..have a look ur self

anyone know how i can change it back to the original please!

do this right click on the desktop>properties>apperance tab>advance button;
click tooltip in the drop down menu, click the bold icon to undo the bold.
from there you can adjust it anyway you like

still the same mate
