When working on a complex image, the Undo function can be a huge help. By default, PHOTO-PAINT sets the level at 10, however you can increase (or decrease) the number of levels by doing the following:
1. Click Tools and select Options.
2. In the left pane, expand Workspace and select Memory.
3. In the right pane, make sure that the Enable undo list checkbox is checked. Input the desired number of levels into the Undo levels textbox (a value between 0 and 99).
4. Restart PHOTO-PAINT.
5. Click OK.
