Copy and paste
I used to use and old version of Photoshop but I had to download the 2018 version.
I am trying to do some simple copy and pasting and I can't do any.
First I tried using the selection tool to select what I wanted to copy and then went to edit--copy but the copy function was not hilited and did not copy.
I also tried to use the selection tab at the top. I clicked on select all and then tried edit--copy but once again copy was not hilited and it did not copy.
I am new to this version so I don't know if I am doing something wrong or if it is a problem with the program
Thanks
