Not really a bug. Just for info in case you are playing around with geometry:
My laptop has 1280x768 pixels, my external lcd 1600x1200. If I stand-by (XP, Rainlendar running) from laptop and start with connected lcd, I get a funny effect on 2.2 (b46) - which I have not noticed on previous builds.
When I change the months (buttons with Global_ShowMonth...), the windows (todo, event, month, dual-month) jump on top of each other. It is as if they are confused as to where they live and return to default. I move the windows back in place, and next time I try to change windows, they jump back. I restart R2, no problem.
Not a problem, actually it is quite funny. (Also, it could be my skin, I guess, will check with standard skin later).
