avant-window-manager doesn't autohide

[Yuelin Li]

I recently installed avant-window-manger on two computers. One computer is an x86-64 platform (AMD Athlon) and the other an i386 (Intel Dual-Core).  The problem is, on the Intel machine awm does not autohide, it just hides behind the opened windows.  On the AMD machine it hides beneath the bottom edge of the display and nicely comes up with a mouse-over.  I checked off "autohide" on both machines.  Both machines run metacity, compiz, and gtk.  I used identical scripts to install avant-window-manager (see below).  Neither machine uses proprietary drivers.

However, the AMD machine is a stand-alone machine with a 19-inch display.  The Intel machine is connected to a 21-inch display via a USB KVM swich (Network Technologies, INC). Can this be the cause of the problem?  Is there a workaround, e.g., by editing the X11 configure file?  I searched the ubuntu and avant-wiki archives but found no answer.  Many thanks in advance,

Yuelin.
