Icons on the buttons keep changing... WTH?!

For some reason, when I set the Enabled property on cmdPlay to False (it's a graphical command button), the play icon I used turns into a Stop icon. Same happens when I set cmdPause.Enabled to False, only it happens with the Pause icon. When I set their Enabled properties to True, they return to normal. What's wrong?

NOTE: This happens at runtime, not design time. And I don't add the code in, I just set their settings manually from the IDE.

By any chance do these buttons have the DisabledPicture property set to a picture or icon?

I did forget to check that, but I just checked it, and it says None.

This is the strangest thing I've ever seen, and I have seen VB do weird things with programs before.
