Kukurykus, I am sorry if I have not been clear enough. And I am sorry that I do not remember the exact dates and version numbers where my problems first began. See screen shot below for my preferred workspace. The "not enough room to display" error began a couple updates ago and I began a thread about it on this forum at that time but no one seemed to have advice that worked. I tried googling around for similar problems but couldn't find any easier solution than to re-install photoshop. Because I am a professional photographer and need to get back to work, I decided to do that. I unstalled and then reinstalled whatever version was available through Creative Cloud. I rearranged the workspace back to my liking and went forward. I did not look to see what exact version I installed. Things then worked normally for me, even through another update, until I was rearranging actions in the actions panel. That required making the panel wider to be able to read the actions' names, which also meant moving the tool panel out of the way. Suddenly the "not enough room to display" error began again. ( I had not yet encountered the tiny image problem since it was not possible to know at what size they were opening since none would open at all.) I then came back to the Adobe forum, did some more googling, and learned about the potential solution to be gained by moving the tool panel back to its default left hand screen position. I tried that (undocked) and yes, it worked, images would open again. I decided to experiment with the position of the tool panel. I moved it back to the right and shifted it around until I found a location that allowed images to open. Then update 19.1.3 came along and images would only open in a tiny little window at the bottom of the screen. As you see in the screen shot, my preferred workplace set up is with tool panels on the right. None of them are docked. In the lower left corner of the screen is an image I just opened. If I move my tool panel back to its default left side location (undocked), images open at their normal size. Also, if I move the tool panel back to the right, but not in a place that Photoshop approves of, I again receive the "not enough space" error. Moving the other panels doesn't seem to create a problem, only the tool panel. I really do like my tool panel on the right side of the screen, it is far more efficient for my extremely right handed self. I hope I have explained myself better this time.
