Problem with blinking monitor occurs only if I'm using dual head (Xinerama) and if Lotus Notes performs "refresh Notes configuration settings". If I'm using notebook's LCD only no problem occours
I've read somewhere (don't have the source around) that it's a known bug, and can be fixed by some driver setting.
(excluding annoying "err:win:DefWindowProcW called for other process window 0x10020")
That message is harmless, and just indicates a bug in Notes.
