I have a recent problem with the last update to Lightroom in that whenever I edit a single photo and then try and do something else Lightroom becomes unresponsive. All I can do now is GP Lightroom as it will not come back and work at all. I'm using Windows 8.1Pro for my OS and the latest version of Lightroom CC. The folder where my source CR2 files are has 400 photos although I have found that it happens in any of the Library gallery's that I try and select.
Has anyone else had this issue and have a solution?
So far I have tried the following.
1 - validated updates to CC, PS CC, and LR CC.
2 - uninstalled PS CC and LR CC then reinstalled them
3 - created a new Catalog
nothing has worked so far.
I suggest that you disable GPU acceleration in the Lightroom preferences and see if that makes a difference.
I literally just found an article that said the same thing and that is what worked for me. Love how AMD and Adobe play well together for GPU acceleration.
