I am using the CMFCEditBrowseCtrl and display my own icon.

There are times when I want to disable the control (ie. m_control.EnableWindow(false);. But it does not behave as I expect:

It is disabled, but the icon does not grey out. And this looks weird I think. What is the right way to address this?

This is how I assign the image to use (during OnInitDialog):

m_editMainBibleReading.SetBrowseButtonImage(IDB_PNG_STUDENTS);
