I have just discovered brushes. They are the coolest thing! But I'm having trouble loading new sets. I have downloaded a few and I want them to show up in the drop down list, but when I try to load them through the Preset Manager they load into the active set. Eg. I have a Disney set that I have tried to load, but if "Default" is showing in the window when I click on Load, they load into "Default" instead of showing me "Disney" in the list. What am I doing wrong?
