I am having the same issues with pages 2 and 3 of Factotum, so it is't your computer. Luckily, the cut off parts are stated elsewhere in the piece so they can be penciled in.
I enjoyed some of the pieces, but a few of them wouldn't display properly. The bottom line on the 2nd Clarinet part was cut off at the ends of some pages, such as pages 2 and 3 in "Largo al factotum". I don't know if this is just a problem with my computer, or if other people have had it, too. Other than that, these are great pieces, and quite challenging.
