Please try to Disable Graphics Usage in Lightroom from Edit>>Preferences>>Performance>>Un-check "Use Graphic Processor"
Let us know if that helps
Thanks much. That seems to have done the trick. I only process two photos after unchecking "Use Graphic Processor", but no trouble. I'll return if it recurs.
Lightroom works faster with Windows 10, but it keeps crashing. Any comments?
