    What is the maximum number of photos that I can stack into a group?


      On Windows 10, second gen Core i7 with 24GB of RAM using Lightroom 6.1.1.   Trying to stack a little more than 1000 photos.  Lightroom becomes unresponsive at first, then appears to have completed the task, then according to the Task Manager ~16% (4 cores hyper threaded) CPU utilization, 2.3GB of RAM used, no hard drive activity.  This last for hours if I let is sit (watched a movie).  Exiting Lightroom, it disappears and continues to consume CPU until I kill it.  Start up Lightroom again and no stack take place.  Tried this multiple times.  Tested with a clean catalog as well.
