If show-paren-mode is on and the first character of a window's buffer is a parenthesis, then if ace-window is called when the cursor is on either that paren or its closing paren, the window-select character for that window will have show-paren-mode highlighting. This is not a huge deal, of course, but it's slightly annoying.
To reproduce:
Open more than one window.
Open a new buffer and type in ().
Place the cursor in that window after the second paren (or on the first one).
Call ace-window. The window-select character for that window should be highlighted.
