Not responding after multiselection

[LeoDE]

After selecting one photo, Lightroom CC shows not responding for a second to three seconds. After that, it works just fine.

Pressing shift and selecting a second photo (multiselect) causes that error to appear for a longer time.

Error occurs with graphics card enabled and disabled.

Are you selecting in the filmstrip or in the grid?  Are you in Library or Develop?

[LeoDE]

I am working in grid mode and (therefore) am in the library tab.

Also, do Help > System Info and report the exact version of LR you're running.  (LR CC doesn't always keep itself properly updated.)

Some initial troubleshooting steps:

- If your current version of LR isn't CC 2015.10.1 / 6.10.1, update to that version.

- Make sure the Metadata panel's current tag set is set to Default.  There used to a be a severe performance bug that slowed down selection when other sets (e.g. EXIF or IPTC) were selected, but that was fixed (at least for most of us) a long time ago.  Maybe the bug has come back.

- Reset LR's preferences: https://www.lightroomqueen.com/articles-page/how-do-i-reset-lightrooms-preferences/ . Sprinkling that magic fairy dust often fixes things when LR goes wonky.
