Updating catalog/stylesheet hasn't updated styles everywhere

[Dasclemawras]

Hi:

 

I have updated the catalog/stylesheet for my store, but doing so hasn't updated the styles in the dropdown manufacturers' and currencies' boxes on the front page of the catalog. Does anyone know where I can go to bring the style in these dropdown boxes into line with the rest of my site? I really appreciate your help. I'm brand new at all this!

 

thanks, Dasclemawras
