I've been having issues with LR 4 of late. The Develop Module is insanely slow and the Import Module completely freezes. I don't think it is an issue with my system (Win8, i7, 32gb) as all other programs purr.
I've removed the preferences, which didn't work and all updates have been installed. Someone mentioned that the usb ports could cause problems and I haven't had the chance to disable these and test. But should I have to? Shouldn't they work with LR?
Everything worked perfectly until ablout 2 weeks ago. Any thoughts?
