I create numerous Acrobat PDF files from MS Word documents via Acrobat 9 Pro. I often need to print a single page from an Acrobat PDF file.

I normally use the keyboard shortcut Control-P (Print Dialog) and ALT-U (current page). I recently set up a new PC with Windows 7, and this shortcut combination does not work. When I press ALT-U, it moves the highlight to the correct item, but does not select the radio button. If I press the Enter key, then I print the entire document instead of the current page - VERY annoying!

It looks like there is an error in the design of the Print dialog for Acrobat. There are two items which have ALT-U as the keyboard shortcut. They are "Current page" in the Print range frame, and "Summarize comments".

I have been able to use Control-P (Print Dialog) and ALT-U (current page) with no problems on virtual machines and older computers running Windows XP. Maybe I installed some software on the new PC that is messing up the keyboard shortcut. Is there any way to figure out the culprit - or is this a known problem with Acrobat?
