We have a few users that experience blank pages or a pop-up with no text and only an OK button when trying to open an Adobe (web) Form with Adobe Reader 9.0 or 9.4.2 or 9.4.0 on Window 7 and I.E. 8. Adobe Reader X is not an option since it is not supported within our firm. Does anyone have a list of the compatible Adobe Reader Versions for Windows 7 and I.E. 8. I'm sure this is highly unlikely, but does Adobe have a matrix that indicates the compatible version according to O.S. and Browser?
