New installed LR 6.2.1 on Windows 7 (upgrade from LR 5.6).
Screen freezes totally and I have to stop LR. After restart it is not possible to use LR anymore.
Uncheck the Graphics Processor (AMD Radeon HD 6570) - no difference
Uncheck the Option "Show add photo screen" - no difference
I have the newest software and drivers for the GPU.
I am not sure, but it looks like the problems starts after importing new pictures into an existing LR-catalog. Before that it works fine.
A new install doesn't solve the problem.
More info: I just tried upgrading LR 5.6 to LR 6.1.1 and I end up with the same problems.
Thanks for your reaction.
The reset didn't work.
As I mentioned in version LR 6.1.1 I have the same problem, So using this is no solution.
At this moment I got back to LR 5.6 again, That works fine.
Problem seems to be solved in LR 6.1.1
I did a new upgrade to LR 6.0 again.
Unchecked use of GPU (only possible after shut-down GPU).
Then upgraded to LR 6.1.1.
At this moment it's working.
