I've been trying to download the clarinet parts for the Gilbert and Sullivan operetta "The Pirates of Penzance." When I select the file, the PDF viewer will only display the first two pages of the document, and when I move to the second page, Internet Explorer 9 freezes up and requires the Windows 7 task manager to close it. I've tried other parts in the same archive and have gotten the same result, but it doesn't seem to be happening if I open an archive for another composition. This problem did not exist less than two months ago when I first tried to download this material. Any help that anyone can offer would be appreciated.
