setting Enabled to False don't change appearance of TGRButton right away

What steps will reproduce the problem?
1. add TGRButton on form
2. add some other control and define OnClickEvent for it
3. add thsi code into the Event : GRButton1.Enabled := not GRButton1.Enabled;

What is the expected output? What do you see instead?
1. If you click second control you see it "disabled" only after you move
cursor on top of the GRButton1
2. Enabled = False will cause button to be Sunken/lowered, I would like it
to stay raised as it is as enabled state. (See attached image) 

What version of the product are you using? On what operating system?

Please provide any additional information below.
