Freezing a visible window to mouse down actions

Is there a way to freeze a visible window so that no “mouse down” actions will be recognized while the user enters data on a different visible window?

I can transfer control easily to the second window, but the first window, if left visible, seems to recognize mouse down actions and interferes with activity in the second open window.

Thank you.

I would make the second window a modal dialog which would lock the first window until the second was closed.


Thank you Wayne - a simple fix that worked perfectly.
