but no additional memory is used because the bitmap panel area had already been allocated.
whoa.. so each panel is in fact a real bitmap w/o an image?
So, a panel of 128 x 128 (RGB-)pixels w/o an image does take up (128*128*3) 48kb of mem ?
ps. 20 canvases for 20 labels (or 'gadgets') = overkill ? See my gadget tutorial in 'tutorials' :)
