How to make group field text disabled when group field is disabled?

Question

I ran into a problem with group text. I disabled the group package by calling EnableWindow (FALSE). The problem is that the group header does not turn gray.

Can someone please tell me why this is happening and how to get rid of this problem.

The same dialog using visual styles:

Both Windows 7 and Windows XP suffer from the same problem, I did not check Windows 8. I am afraid that we must put up with this. The only way is to draw a group box yourself.
