P: Select > Sky command won't work

Works great, what was the issue? The flux capacitor or did the warp drive need dilithium crystals?

Works great, what was the issue?  The flux capacitor or did the warp drive need dilithium crystals?

For me the behavior is too bizzare to screenshot, mainly because I use PS for pasting screenshots into new documents but I can't do this after attempting to use Sky Replacement.  Here goes ....

I open image and go to Edit>Sky Replacement.  A spinning circle of death appears on the new popout window for Sky Replacement and then I get the same error message as jdoodle333 but without the option to "Learn How to Fix."  I take a screenshot and try to open a new document (sized for the clipboard).  When I do, it makes a copy of the first document I was working on.  When I try to paste the screenshot over the new duplicated document I get another error message saying, "Could not complete the command because if a program error."  At this point I have to restart PS.  When I go through the aforementioned steps again, without taking a screenshot and opening a new document, and try to use Sky Replacement for a second time it sometimes will replace the sky on a new layer and sometimes it will create a new layer that is blank.

Hi, could you share screenshots of they steps you are going through to see this error? 
Thank you for uploadingy your system info, the team can use that to make sure nothing is out of place that might cause this, but the visual images of the steps you take to view it will help them diagnose where the issue originates.
Again, we appreciate your patience.

Have asked engineering to look into this issue.

Hi Jdoodle333,

Have asked the team for info on this issue. 

Could you share your system info: In Photoshop, go to Help/System Info, then copy and attatch the file here?

Thank you,

Just tested and it's working for me... what are the steps you are taking? Can you be more specific about what you are working on? Have you completely logged out and back in to the program?
