You are talking of the xwin driver, right? The tk driver doesn't have=20
such problem. If you don't like the menus in the tk driver just hit the=20
"m" keyboard key to toogle the menus on/off.

As for the xwin driver, I have solved that problem in my sources using=20
threads. The threads approach solve the problem for compiled languages,=20
but not for all interpreted languages, as the interpreter must have=20
been *linked* with -lpthread. My python's distribution was linked with=20
pthread, and works fine. Octave is not linked with pthread and fails,=20
you have to relink it with pthreads and then it works OK.

You have to wait a little more to see this improvement, as I don't want=20
to mess with plplot until the next release.
