I have a simple form (not main form) with a WebBrowser control and a StatusStrip. The WebBrowser Dock property is set to Fill. In design mode the WebBrowser behaves as expected and expands/shrinks with the form, stopping at the StatusStrip which simply travels with the bottom of the form (and varies in width with the width of the form. In run mode, the StatusStrip still behaves as expected, but the WebBrowser does not increase in height with the form, leaving bare form exposed. What is going on? How do I fix it?
