The gui_error window caption is now simply 'RelaxError' rather than the specific relax error name.

This now matches the prompt/script print outs which only have RelaxError, unless debugging is turned on.

Fix for the NOE spectrum loading wizard - the comboboxes need SetStringSelection rather than SetValue calls.

SetValue and GetValue on the read only combo boxes seems to fail on Mac OS X.

Mac OS X bug fix - the busy cursor is only turned off in the gui_raise window code if the busy cursor is on.

Mac OS X bug fix for racing in the GUI interpreter thread.

The flush() method was not working properly on Mac OS X, so hopefully now it is thread-safe. There
are conditions where it could fail though, and the current solution is a bit of a hack.

Bug fix for Mac OS X for the spectrum.replicated GUI user function.

A GetValue() call fails on Mac OS X for a read only wx.ComboBox if no value is set!!! Stupid Mac!

Fix for the Rx auto-analysis GUI test for the changes to the spectrum.replicated user function GUI page.

Another Mac OS X test suite fix - the spin viewer window menu bar is now no longer set in the gui tests.

Bug fix for the test suite under Mac OS X - the GUI's SetMenuBar method is only called if status.show_gui is set.

This prevents the menu bar from starting when running the GUI tests.

Bug fix for Mac OS X - the timer in the relax controller is started with a wx.CallAfter() call.

This is to ensure that it will start from the main thread, which is essential!

The GUI tests in the test suite no longer have IO redirected to a window in Mac OS X and MS Windows!
