In the Library module, I do double click on any image, and start the selection process, pressing the "x" key to reject the images that I'll not keep.
On previous versions, each time I reject an image, the next one was autoselected and visualized. In the v11, after reject 3 or 4 images, suddenly the next one image is not selected. So I've to comeback to the grid mode, and reselect the next image. This makes the whole image selection process really slow and frustrating. I hope you solve this issue as soon as possible.
