Hey Martin - sure. That cr2 is correctly typed. meaning it doesnt have any typos (that would also stall my PC) - and it works here. Now I didnt expect any thumbnail to show on his machine - but the shrugging figure that shows on the PC WHEN you have both cr2 and obj at the right place BUT no rsr. See what I mean ? Stuff is tested, but he gets nothing ? He also keeps telling me Macconverter wouldnt touch any library files - that is why I am trying to solve this problem anyway. I cant really check on this right now as Microsofts new MacEmulator TM is still a buggy beta :) So I thought before I told him he was completely wrong... Do you want to check the file maybe ? Thanx, Pete
