Is there a bug using some of the options. In Select a lot of options are greyed out. Image is in RGB and 8 bit. Size of document is 8x6 inches 300 resolution. I checked the adobe forum and there seem to be a lot of people with the same question but no solution.
A bit embarrassing. I had been working on my photo edits way too long and had somehow deselected a selection without realizing. Then spent about 2 hours trying to figure it out before I went onto the forums!!! Received an email asking if I had a Selection and I was thinking - yes - and then when I triple checked - No! Thank you for trying to help me sort out my dilemma. Feel a bit of a goose, but pleased it was my brain fade rather than a but - as now I can get back to editing :)
