 432 Mac Implementation note :
 433
 434 The Mac has only one global menubar, so we attempt to install the currently
 435 active menubar from a frame, we currently don't take into account mdi-frames
 436 which would ask for menu-merging
 437
 438 Secondly there is no mac api for changing a menubar that is not the current
 439 menubar, so we have to wait for preparing the actual menubar until the
 440 wxMenubar is to be used
 441
 442 We can in subsequent versions use MacInstallMenuBar to provide some sort of
 443 auto-merge for MDI in case this will be necessary
