If you have ever reset your workspace in Corel PHOTO-PAINT, hopefully you didn't have many custom brushes. If you did, they were gone forever. Before resetting your workspace, you'd better save your brushes together with your entire workspace to a new file by clicking Tools-> Options, and then clicking Export on the Workspace page.
