Mac DeBug alert

I've been running the new version of BeerSmith for MAC just fine, and a few days after I upgraded to Beersmith2 I get a "wxWidgets Debug Alert" every time I open BeerSmith2.  I have tried reinstalling and still have the same problem.  
It has a "cancel option to suppress future messages"  but it still pops up on every new startup of BeerSmith2.

I've attached a screen clip of the warning.
Thanks
Don

+1.  I get this error message when I try to change the "look and feel" settings.
