I have Acrobat XI Pro (latest updates installed) running on Windows 7 (x64) Enterprise. It has worked fine for a while, but recently began to experience it would stop responding to mouse clicks if I let it sit idle (lose focus) for about a minute. In other words, I can open a PDF document using Acrobat XI Pro and work with it with no problem, but if I leave the document open while switching to another program (any program like Outlook or Windows Explorer, etc...) then try to switch back to the PDF, it will not respond to any mouse clicks and I have to end the process in Task Manager in order to close the PDF.
I did notice I do not have this problem if I open the PDF in Adobe Reader.
Help! This is driving me crazy!
