I'm running LR 15.3 on a Win-10 PC, just beginning to explore the program.
When I try to import images the system (info below) appears to freeze for 1-5 minutes. Eventually it unfreezes and I'm able to start work in a normal manner, but this happens regularly whenever I try to import images. It makes using the program very difficult. I don't have similar difficulties with my other CC programs.
I'm suspicious that the source of the problem may be my Sonos speakers, each of which appears as a separate device in the file tree (I have seven labeled K, L, P, Q, R, S, T). Other than that I'm baffled. Any suggestions would be welcome.
