Running Windows 7 RC. Running Adobe Reader 9.1.0, downloaded from Adobe for Windows 7. I am able to read PDF's that are saved on my local system. When on the web and trying to read one, It opens a new window, I get an Adobe error message pop up that only has a "?" and an "ok" box. Click on the OK and get a blank window. This happens on all PDF's I have found on the web. Have tried it with IE8, Firefox, and Safari with all the same results (IE no message but never comes up). Anyone have this issue? Or have a solution?
