Ok guys ! Thanx a million for all the help & tips. :) I found the problem... it was a set of 9 freeware plugins I got off the Computer Arts magazine's cover CD... I think they might have been only for the mac, but as soon as I removed them, everything was 100%. And as for buyng a G4 ?? Not on my salary.. hehehe... Thanx guyz ! Luthor :)
