Any way to disable move maximized windows?

[S.W.B.]

Hello,

My biggest complaint about XFCE (actually xfwm4) is that it allows you 
to move maximized windows.  All day long I find myself going to scroll a 
window from a scrollbar on the right side, and I end up grabbing the 
window border instead and resizing my window.  It is exquisitely 
irritating.  To the best of my knowledge, there's no way to disable 
this, whereas in Gnome and KDE and Windows, it's not allowed by 
default.  That's the way it should be.  Yes, there are mousewheels, but 
many people running Xubuntu have old hardware, and old laptops, with no 
mousewheels.  This is such an irritating problem, that it almost 
justifies hacking the xfwm4 code to fix it.

Thanks!
