mspaint

at school when im messing around with paint(i dont know what os, 98 i think ) if you hold the + or - key, the eraser/spray thing/ brush thing gets bigger or smaller, but when im at home on xp pro, it doesnt do it. Is there a way to make it do this? Can I download a patch for paint(hehe, go to microsoft and check for vital updates, download the vital mspaint patch that adds 4 new colors that are microsoft exclusive!!!)

might try taking the paint app from 98 and overwritting the new one. Thats all I can think of.
