this one: http://wakaba.c3.cx/releases/mac/Xee2.0beta1.zip
problem exists even with a clean cx.c3.xee.plist
It also occurs with a "clean" account (in this case root which isn't spoiled by any customizations); The "L" is funny as it really gets multiplied; I set horizontal and vertical mirror to "H" and "V", which are kept after a restart of the programm but doesn't work
I haven't tested it yet on intel mac
