Resource leak in graphics system?

[Peter-Henry Mander]

Hi everyone,

I've a query about the memory usage of the graphics system which appears 
to grow without end! The offending processes are gs_frontend, gstk, and 
et_viewer. Is there something I ought to be doing to plug what appears 
to be a resource leak? Is there a simple way I can ensure that a node 
will not employ any graphic system? Is this a known "feature" of Erlang/Tk?

Pete.
