Microsoft Windows limitations

On Windows, you cannot use the Undo and Redo shortcuts repeatedly unless Penpal is docked, because it causes the panel to lose focus. The other shortcuts are not affected in this way. If you are on Windows and you prefer to use Penpal floating, you can use the undo and redo buttons in the footer bar.
