Hey Guys
I am attempting to create a TPanel that responds to a mouse up event to change it's background, Text color and track it's current state. Below is the current state of the component. The component is responding to WM_LBUTTONUP but the component continues to capture the same message even when it not clicking it.  Any input would gladly recieved
