Where is the eraser tool?

All you have to do is painting a canvas with a background color.

GraphicsGale treats one of colors as transparent area.
Layers and frames can have their transparent color.

If a transparent color of a layer is set, the area filled with that
color is transparent and its under layers are visible.

A transparent color of a frame is applied as a transparent color of an
image file which supports transparency such as a GIF.

Why is a transparent color invalidated after a selected image is fixed?
