We have a problem on multiple computers in which to open pdf documents it remains hung in appearance. Actually the application does not crash, but it takes 20, 30 seconds or almost a minute to open the document.
The computer is new, with XP updated.
It happens at Acrobat X Pro updated to the latest version or outdated.
The user does not have administrator permissions.
Files can be even a page, do not have to be multipage. It happens also if the file is in a network folder, from the mail, or from the harddisk. It's very usual and when it happens, there is no process expending cpu or ram resources.
The problem occurs on multiple computers.
