Cassel both ways of selecting all work i.e. Ctrl-A or Selection> Select All. Once I have selected all, locked the transparency, and then go to flood fill the tool simply does not work … the marching ants are there and the active tool is flood fill, but no go. The paint brush works just fine with or without Select All as long as the transparency is locked. I don’t want to spend the time filling individual little pieces so I am content to do a sweep or two with the paint brush. I always have PSPx7 open and the steps work fine in it so for me it appears to be a glitch with 2021. Thanks for your consideration. 😉
