title: Allowing a title bar double click to maximize a dialog but without max-min buttons
body: <p>This is a little C# specific. The default behaviour of a resizable dialog box is that a title bar click maximizes the dialog and a second double click restores the size. However, what I want is to have the Help button turned on, which means the minimize and maximize buttons are hidden, but I would still like the title bar double click behaviour. This might be achievable with some subclassing, but perhaps someone has some good ideas on this.</p>
