Save Image As... no longer working

Recently updated to portable 1.5, and I can no longer do a "Save Image As" The option is there, but there is no other reaction. I somehow doubt that it is because of the new version, because I believe it was working even afterwards.

Adblock was blocking certain Flash elements before, but the pictures I want to save come up fine on the screen. I can drag and drop to a folder or desktop, but otherwise, the menu option to Save Image As simply doesn't work.

Anybody run into this?
