thanks for repley, anonymous_user, but this isn't easy as it seems. -> this works for the background - thanx but: the problem is, that, after i logon (insert password+return) the logon-window turns into black (gets xpized). on the picture it's blue. same with background (solved) and same at logoff - the black window gets blue + blue desktop. so i supose the theme is load after login and unload by logoff. may there be a way to change the very standard theme? i'm not an expert in skinning windows due in other windows stuff ;P. so someone another idea? thanks!!
