embedded plots in xMaxima



xmaxima 5.11.0 gcl 2.6.8 Windows 2000 gnuplot 4.0

Trying plot2d(sin(x),[x,0,6]) in various plotting modes:

Plot windows: embedded
     Does not embed plot; makes separate window.
     Echoes user input in xmaxima window,
     but does not respond to it until plot window is closed

Plot windows: Separate
    same thing

Plot windows: Multiple
    same thing

In plot windows: multiple,
    (plot2d(sin(x),[x,0,6]), plot2d(cos(x),[x,0,6]) ;
    first plots sin, and only when window is closed does it plot cos.
