I know it seems silly, but I had a need, and since it has now been an issue I have seen for some time, I guess it is time to report it.

if I am Attacked and goes into Combat, the bag closes, but I am unable to open it again and it gives the following error message:

Message: [ADDON_ACTION_BLOCKED] AddOn 'Bagnon' tried to call the protected function 'BagnonFrameinventory:Show()'.

Thanks for this, I like it better than the alternatives.

I think this one was probably fixed by 8.1
