I am using IE 8 (version 8.0.6001.1882) and I am able to open a PDF from a website the first time just fine. But if I close the PDF tab/window and then click on the same PDF link, IE hangs. A new tab/window is opened and it looks like the PDF is downloaded, but the window remains blank and is unresponsive. I have IE set to open the PDF within the browser in a new tab, but I also have the same problem when opening the PDF in a new IE window. The version of the reader I am using is the one that came with Acrobat 9.0.0. I am running on Windows Vista. Any help with this problem would be greatly appreciated. Thanks.
