I'd make this a poll, but polls can't include images.
Firefox. I have clicked "ALT" on a post image and the pop-up alt-text window contains more text than will fit. I have hovered the mouse over the empty lower section of the scroll bar (you can see that it is fully expanded; I have indicated the mouse cursor with a "+").
What will happen when I click the lower section of the scroll bar?
1. Window scrolls and stays open.
2. Window scrolls but instantly closes.
