Indesign CC 2017 is crashing when switching apps on El Capitan, iMac mid-2010 w/16gb RAM, especially when the <Command-Tab> is used.
It seems to crash less frequently when the other app is selected from the Dock.
It does not crash while the app is in the foreground, but may crash immediately after the switch, or randomly while in the background.
I have deleted the prefs file, to no avail.
Photoshop, Lightroom, Illustrator and Acrobat (all open) are unaffected by the problem.
