My lightroom has been very slow taking a long time for exporting and it also keeps logging me out when working in lightroom. It has been taking me about 10 minutes just to edit and export a photo. Please help!
Regarding the export related issue, where are you trying to export the images? How many images are you exporting and format, size are these? Would you mind deselecting the option "Use Graphics Processor" located in Lightroom's Preferences > Performance, then relaunch Lightroom and let us know if it helps?
