So, I looked into this a little before asking.

Basically, I always select the entire canvas, and modify my selection for multiple Photoshop effects. It has never given me problems until just recently. Now, if I select the entire canvas, Photoshop will gray out the modify selection options. People online claimed that you can't select the entire canvas, but that is how I've been doing it for years.

So, does anyone know how to stop the selections from graying out? I don't want to have to expand my canvas each time I want to create borders, etc. I need a work around, a method, anything that will stop these options from graying out like they currently are.

Thanks.
