Upon starting Mathematica 6.0 under compiz, in addition to the usual Mathematica windows I get one large extra window, which is empty (painted white), has blank titlebar and cannot be closed (although it can be resized). When I start doing calculations a second extra window appears. These extra windows are absent under other window managers e.g. kwin. This problem has been noted by a few others, e.g. http://bugs.opencompositing.org/show_bug.cgi?id=5 http://forums.wolfram.com/mathgroup/archive/2007/May/msg01137.html I am using Gentoo and the binary nvidia drivers, xorg 7.3 and a recent git version of compiz (with the compiz-fusion plugins).
