I am running the latest version of light room. While in the import window, I cannot use teh left and right arrows to go between pictures, on the camera, while in loupe view. I have to keep going back to grid, select a pic and then go to loupe. I am convinced that the arrows are in fact moving between pics, because the "select for import" check box changes accordingly, but the pic does not load.
I am able to reproduce this problem. Doesn't have anything to do with your BP monitor, it happens even if the camera is the only connected device. Looks like it happens only with a directly connected camera (not a card reader or hard drive), and only on Windows (not on Mac). I've written the issue up in our bug database (bug number 3950225 for internal reference, since the "private tag" feature doesn't seem to be working on this page at the moment). Thanks, Ben
