Re: Windows mingw64 - loading of certain Gorms broken - NSSearchField ?

[Fred Kiefer]

Thank you for finding this. I made a mistake when I changed the encoding to use 
our new helper functions. For strange reasons an unsigned int had been used for 
the maximum. Should be fixed now. Hopefully no Gorm file was created in the 
meantime.

Cheers,
Fred
