mouse pointer in and out from commandbutton's area detection

[zz]

i need to detect whenever the mouse goes in or out from a commandbutton in
order to replace the picture displayed on the commandbutton, mostly for
design purposes

i have tried detecting it in the mousemove event o the commandbutton , but
this makes the button to look like blinking, in the classic VB i had the
mouse in and mouse out events, is there an undocumented way to implement
this in VBA?

regards
