Trouble Reading Disc...


I recently installed tiger & have so far encountered only one problem. when i install a dover desk gallery disc full of clip art images i get the spinning beach ball of death. it lets me click down thru the folders but when i get to the image list it stalls & i get the beach ball. if i wait long enough the tiff files eventually show up but if i try to scroll thru the list to get to the image i want the beach ball pops up again and i eventually have to relaunch the finder to unmount the disc. i tried the disc on my husbands computer which is still running the first osx & the list popped right up no problem. any advice?
