AME 5.5 Locks Up when you access output location using Windows 7 64bit Explorer

Question

I often queue up a few dozen things in AME 5.5 from PP 5.5 and hit the start button.
After a few have been successfully encoded I open the directory where they were output and I start zipping them up into another directory and/or moving them to some other drive.
AME will inevitably stops working at some point while I'm playing around with files it should be done with - it just jams up - no error - no warning - the Elapsed Time just stops counting up.  No predicatable point - not beginning - not ending - somewhere random between - somewhere right about when I started moving files around.
Stop button does nothing...it doesn't stop.  ProcessExplorer kills it nice though - and then you can see 50 adobe components run off and hide...

Between the red above is where I killed the process (after closing BR,PS,PP,AU.......).  The blue shows the same reset job encoding just fine - once I keep my nose out the output directory.
I've taken to doing File/Save Queue before pressing start now.  And before killing the process once this happens.  Usually it comes back up having erased any entires that were encoded and marking the one that was jammed up with skip.  I manually delete the partial file
Windows 7 sp1 64 bit CS5.5 Master (updated?  have there been updates?  Help says none.
What's AME problem with me poking around where it's encoding?

No, we are unable to run different browsers at the office.
