Bitmap/grayscale bugs
I am finding all sorts of problems working in Grayscale with the current version (2017.1.1). After converting to bitmap, if I copy and paste that image into a new grayscale image, Photoshop won't allow me to do anything _(such as save, export to PNG, drag the layer into another window) "because of a program error". If I copy the image and paste into a non-adobe program (such as Preview), it is reversed black/white. If I try to create a new image in Photoshop with a white background, it has a black background. If I try to convert the pasted grayscale image to RGB, Photoshop crashes (this is completely repeatable, every time). There is nothing I can do except to quit the program and start again. Clearly something goes very wrong after converting to bitmap.
