There may be an MS runtime DLL that you need in order to get easymove.dll to work. OTOH, I've had some problems with easymove causing crashes on recycle, presumably due to the mouse hooking, although I don't know for sure. I've changed things so that the module isn't loaded at startup, but can be loaded on demand (hotkey or on-screen toggle). I'd just comment out the NetLoadModule line for that module right now, pending a permanent solution (which might be "don't use it!"). The module isn't really an integral part of the theme, it's just a utility that I've found handy when working with certain programs that insist on positioning windows where you can't get at the titlebars.

As far as the math errors go, what xcal said. That's why I say you need to use a new build with those themes (penumbra, chameleon). =)
