Yes, i think that i can explain - but not fix
There is a bug. BST recently fixed and then broked the grabbing a little again... So far, now it for me working only when the conversion gadgets is unchecked, hehe :roll:
Well, they SHOULD BE checked, but... it works a bit reversible now :lol: :?
Anyway, the resized grabing it broken the same way as this - i assume. Try play a bit the the settings, if you can't find a workaround.
Personally i don't see reason, why grabing resized images, so, i don't know how this is supposed to work at all - never tested there... :roll:
