Odd spell check problem

Hello all,

I recently noticed that spell checking no longer seems to be working in  
balsa.  Misspelled words are no longer underlined in red, which was the  
usual indication.  I have selected gtkspell (3.0.7) in both the  
configure/make and meson/ninja builds, and both behave the same.  ldd  
of the executable does show it linking to libgtkspell3-3.so.0.  I was  
thinking of trying strace, but I don't really have any idea what I  
would be checking for.

Fortunately, before I simply posted this, I grepped for spell in the  
.balsa folder, and found "SpellCheckActive=false".  Changing it to  
"true" turned spell checking back on.  However, I have now looked  
through all config options within the program, and could not find  
anything relevant.  Am I being blind, or has it disappeared (assuming  
it was actually present in the past)?

Thanks for any light through the current fog of my brain.

Jack
