You will have to handle this yourself. However, it is no big hassle. All you
have to do is sub-class TIcon, add an instance variable to hold the name, and
override TYourIcon.Draw to draw the name. You may also have to override
ControlArea to allow for a little space under the icon for your title;
normally, ControlArea returns the entire bounding rectangle of the control,
with space adjusted for any adornment you may have. TIcon.Draw takes this
rectangle and scales the icon to it.

Are you putting any of your routines/methods into either the MARes or MAScroll
segments? It is these segments that are put into GRes during final linking.
Looking at the Nothing sample, I see that it is fairly substantial already,
weighing in at over 29K.

The solution to this would be to put your routines into another segment, 
possibly one of your own. If you would like to make this segment resident (as
GRes is), then call SetResidentSegment on it, or include it in your 'res!'
resource.
