Cannot open FT4 2.1.0-rc5  on Mac 

Hi Again,

By the way, 

I have been trying to  open a newly downloaded  Wsjtx FT4 2.1.0-rc5 app on a 
MacBook Pro  running 10.4.4  It crashes every time and I cannot open it.  I use 
the FT8 version all the time without problem.  I have taken care of all the 
memory issues, for the standard version.   Am I missing something?    The 
beginning of the crash report is below. 

Thanks
