Well, when maximized it just doesn't work. Moving the mouse over icons does nothing. When you click on it, it's affected, but actual drawing fails.
However, you can make the window smaller, as normal. It doesn't truly freeze up. When small, it works fine, but it's too big. You can't access the colors, or a lot of lower down stuff. When you click on the view edge to make it smaller, it moves down. You can, in fact, move it down under the mouse's range, and then you can only close the thing.
The only way to use Inkscape is to go back and forth between maximized and small, selecting colors and such in maximized and then drawing in smaller mode.
I have tried deleting Inkscape and redownloading it, but it doesn't help.
