When I create a loop to make a matrix of labels, the background and font colors do not appear right away
when the labels are defined.
I had to create a additional loop to force the colors out. Does anyone know why.
In the code you will see a simple label called "color1" that works properly. However the matrix of labels seems to ignore
the color specs. Three matrix sets are called for, the first has the extra loop to illustrate.
