i have created an icon in 1238 by 128 .png format.. howver i would like to use it as a sytem icon.. if i convert it to a .ico in icon sushi the text becomes fuzzy when in use at normal windows size.. how do people do it so that there are multiple sizes of icons contined within the same .ico.. hope this makes sense

The icon needs to have all sizes (from 128x128 down to 16x16) & not just the 128x128 size.
Probably the easiest way to make this from your PNG file would be to use IconWorkshop

thanks a bundel

I suggest iconsushi

I recommend Iconworkshop for this, its just so easy to create an ico with all the sizes from a PNG using it.
