Capturing the mouse in a %gr window

Is there any 'official' way of capturing and releasing the mouse within the %gr callback (I'm not set_graphics_selection@), or getting the %gr window handle so that the normal SetCapture API func can be used ? I have got it working by using FindWindowEx to get a handle to the 'SalfordGraphics' window (class name) and it seems to work as expected but maybe there's a better way ?

Thanks, Alan

%lc gives the handle of the previous control.

Doh! Of course. Thanks Paul.
