Mac OS X fix for the relaxation data list element - the height algorithm is now more robust.

The ListCtrl.GetSize() method appears not to work on Mac OS X!?! Therefore a different algorithm
has been designed to get around this Mac specific problem.

Fix for the relax_fit.relax_time GUI user function.

The combobox GetValue() call has been replaced by GetStringSelection() for the spectrum ID.

Removed the wx.Yield() call from the spin viewer window refresh() method.

This is to prevent recursive wx.Yield calls on Mac OS X from killing relax. This change might cause
instability though!

Fix for the Rx peak list wizard for Mac OS X.

The combobox SetValue() call has been replaced with SetStringSelection().

Text files in the results viewer window are now opened with a text editor on Mac OS X and MS Windows.

On a Mac, the text file of NOE values was being opened up in 'Saturn', as the file ending '*.out' is
associated with that program.

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!
