Detecting mouse over a button

Do you have a Delphi 1 component that is a button that can detect when the mouse is over it, please?
I have the "MsBitBtn" from the Delphi Super Page (http://sunsite.icm.edu.pl/delphi/) and it works fine but not when it is in a form that is scaled. {form width etc scaled and components in it scaled by MyForm.ScaleBy(screen.width, 640)}. The button need not be a BitButton, just an ordinary button will do but it must -
1. Behave like a normal button.
2. Produce an event when the mouse moves into it or moves within it. I can set a flag and ignore multiple OnMoves once the 'entry' has been detected.
3. Produce an event when the mouse moves out of it.
4. It must behave as if it is detecting the position of the mouse, not the crossing of the button boundary- ie it must be able to respond correctly to fast movement in or out without missing the move.
5. It must work in scaled forms.
The MsBitBtn works well (after removing its 'color change') and would give you an exact idea of what I need. It has source code but unfortunately not for its DLL. The ideal would be to write a DLL for MSBitBtn that works when scaled so all I have to do is replace the DLL.
Thanks for your help.

Does a normal delphi button not work as it has a OnMouseMove event?

Create a descendant.
Add two private procedures:

procedure MouseEnter(var Msg: TMessage); message CM_MOUSEENTER;
procedure MouseExit(var Msg: TMessage); message CM_MOUSELEAVE;

Fire an event in each procedure.
If you don't know how to do that, email me:
