I've loaded a set of brushes I created into CS6. They show up fine in the menu bar brush window, in the Preset Manager, in the Brush Preset palette above my layers palette, but they will not appear in the brush preset fly-out window. This is where I do all the manipulating of my brushes, of course, so this is essential. I have created many, many brushes and done this many, many times and have never had this problem. Any thoughts on what's going on? PS CS6 on a Mac.
