Lightroom 5.3 crashes when exporting pics to a directory on the same hard disk. When right clicking on a file, and selecting either export option, then selecting the folder, Lightroom's screen goes white, and at menu bar on top it says "Not Responding," then it waits and reports it has crashed and asks to close the program. This has been going on for since LR 4 the later versions. I've cleaned up my machine, tried exporting to different drives, and the crash occurs 1 in every 5 or six exports. I'm not the only one experiencing this. Google and Bing searches show many people experiencing it. Any help here?
