Having problems when opening prefs - for either version - both up to date.
Windows 10 x64, along with the latests Nov update.
Two NVIDIA cards - both latest drivers.
Reinstalled R19. Same issue, however unable to update to .068! Hangs!
Ive read previous comments on web, has happened before - some suspect a C++ redistribute - though nothing confirmed.
Interesting I was experiencing the dreaded “not waking from sleep” issue as well. I have resolved that.
So much fun switching from OSX!
