Walter,

You present a reasonable argument, but what about one like this. . .

Don't know why they are bitmapped when MS itself implies that windows controls are 'objects'. Being such would lend them to the possibility of being sub-classed, and it should not be beyond the realm that subclassing at this level would include the possibility to "adjust" the 'boundedness' of a control and to add additional properties, events and methods.

I've certainly heard before that their existence is due to the (now defunct) cross-platform objective of VFP.
