Hi Meador,

I apologise: I really shouldn't have called it a patch. It's just to show one way that I've found fixes the problem (but presumably reduces performance in other cases, hence the suggestion & wait for feedback on the issue). I'm not really experienced with Python (nor am I an experienced / particularly good developer in general) so it's probably safer to treat me just as a regular user who stumbled upon a problem. :) (I'm definitely not shying away from "ticking all the boxes" but I don't see that there is any point in me trying to yet.)

Regards,
VT

PS: I've re-attached the example "fix" with the diff the right way round (sorry).
