I have a problem with some windows that take the wrong position over my screen, they go out form the screen, these Windows are for example "save image" "upload file" "open file" ecc of firefox or openoffice, the windoww where i have to choose a directory and i file like in a file manager, and these windows when i open them, get place out from my screen, i don't understand why this happen. I'm not the only one who this happens fortunately :D
