I really like this program. One problem I'm having is when I copy and paste a path into the import palette field. I paste it to lead to my (F:) drive but upon pressing the enter key it doesn't do anything. Trying to load a gpl file also crashed it. I noticed the paths use forward slashes in the program but on Windows 10 it's backslashes.
I thought you should know about these problems for later updates.
Edit: only some crash Pixelorama, notably the Illu 32 colour palette.
