To be honest it was initially written some time ago and it's various
startup possibilities just ended up in what i have.
I can probably revisit the startup and make it better.
And as bizzare as the structure is it seemed to work. i only just noticed a
problem on mint/mate/qt.

Looking at it now I'm thinking,, why is my startup class even a Form? it
should probably just be a startup.module.


Note that I have just tested with Mint 21.3 + Mate in a VirtualBox vm.
