What computer system are you using?
How much RAM and hard drive space available.
Thank you for your reply.
Intel i7 processor
Over 400GB of available hard drive space.
NVIDIA GTX 950m Graphics Card
Been running Lightroom for about 10 months and never had this issue.
Is the LR option checked to use the GPU? There is a problem with the newest nVidia graphics drives. Roll it back to 36X.X something. There was a post on this forum about a couple of days ago.
I'll try to find it.
Thanks again for your help. Whether the GPU option is checked or not in Lightroom, the problem persists. I only upgraded the Graphics driver after the problem started occurring, so it is still an issue regardless of the graphics driver. It is a stand alone version, so maybe uninstalling/reinstalling might be an option?
Pleased to report that re-installation resolved the issue. In fact Lightroom is operating better than it did before. Thank you for your help. Don't know why I didn't just re-install to begin with.
