I likewise find the Sumatr pdf viewer better. Besides the benefits already mentioned, it also has the proper quality of being non-intrusive. Adobe readers are quite happy to bloat your memory and take control or otherwise intrude on your system's normal operations.
I don't use Adobe's reader at all.
Adobe Reader/Acrobat is the reference: is you see and print a pdf with Acrobat under Windows 8 you are on the right side. Otherwise you are on the wrong side. For javascript, if the pdf works under Acrobat under Windows 8 it's ok, otherwise no. If Reader/Acrobat doesn't complain the question if the pdf is valid or not is not important for and end user (ok, it's not true for pdf/a). Until now I have found the sumatrapdf is (very) good, but it cannot be used as reference. -- luigi
