It happens when 'whatever it is' believes that the word Gunna should be 'going to' in the context its written in though for the life of me why it thinks that 'going to' makes sense in that phrase I don't know.
Why is it not auto-correcting the Wright to write and the Chex to Checks as well?
I even asked my computer system to add the word G unna to my dictionary.
If I type in
as a standalone word its OK
