well I solve it like this ... instead of a normal window, create a POPUP
one (override redirect) for your app window ... I have mouse follow focus
in fvwm ... so I keep the mouse on the xterm running the gdb and then slip
the mouse over to the app window without touching the root (you could use
sloppy focuse for this to be easier :) ... since the app window is overrride
redirect, it will leave focus on the xterm ... then when the breakpoint
comes ... the focus is still on the xterm window
