Thanks Mattias.  I was aware of the defines but thought maybe there was a 
built-in function in LCL that returned an enumerated type or constant or 
something similar.

No problem, I will just create a singleton that relies on the defines to return 
an enumerated type of my own.

Thanks I will look at this.  Does this rearrange itself depending on the OS?  Is 
that what you are saying?  I have not experience with this component.

Thanks again,
