When closing a plan, the “closing document” window opens up immediately and then it  takes several seconds before the “save changes” window opens.  This happens only on the 64-bit system (Home Premium).  The 32 bit system is almost instantaneous.   During the wait for the “save changes” window to appear, the disk I/O flashes continuously.  This is true even for a newly created plan with nothing in it.  To do the comparison, I installed AP on Win 7 32-bit and copied all plans, preferences, etc from the 64-bit system to the 32 bit system.

How big is your plan document file on disk? When you open it, a copy of it is made to the temporary folder. When you close it, data are written to the temporary copy and if any changes are noted, the Save Changes dialog is put up. If you elect to save changes the temporary copy then overwrites the "real" document.

This is not the most elegant method of doing things, and is a legacy of V1 where the plan document format was/is fragile.

Try this for me: create a new untitled document, open the NGC catalogue and add all 7000+ objects to the plan. Save it. See if that document does the same "10 second" open/close thing.

I have both the 32-bit and 64-bit versions of Windows 7 (Home Premium) on separate computers that are located in the same room.  I have over 40 years of computer experience that might be of some help in the debug process.  Just let me know when and how I can be of service.
