Nice work!
Just two things: cmd or control ` isn't easy to do on other keyboard layouts... As silb said.
And the second one; a bug:
Maximize a window, resize it, and watch the pretty redraw issues. It does indeed look like the window doesn't realy resize itself. But it sounds like Bob already found this, no?
Gawd, I'm not even helping, am I? :/
Anyways, here's a new one for you:
Write something in the text bow, change to passworded field, select all the text, revert to normal field, and try re-selecting the already text. It misses some of the selection, and based on the Y position of the mouse, the selection draws oddly:
Edit: I can't recreate the bug, so I probably did something weird... I can not remember if it was after the maximize bug thingie or if I started a new instance...
