Command button problem on lost focus

I have put a command button onto a worksheet. It is just a normal command button not a toggle button.

I've written some code and the button executes the code as exepected.

The problem is that when the mouse moves focus from the button, the button depresses and stays pressed down. Although it doesn't run the code again, it looks wrong!

The button operates as normal when pressed, i.e. it depresses then comes back up again. But no matter what I do, once I move the mouse away from the button is stays in the ‘down’ position.

Can anyone help please?

(I am using excel 2003)

hi rede96
Is it a ActiveX or Form Control Button?
