I had some offline discussion with Eric around this. The problem was that I
had stopped calling RunApplicationEventLoop() function, which installs an
event handler that calls MenuSelect() in response to clicks on the menu bar.
When I switched to Cocoa, MenuSelect() was not getting called. As a
solution, I need to call MenuSelect() explicitly when the menu bar is
clicked. This solves the problem.
Thanks for all the help.
