Has anyone been able to use the Pmw.Blt megawidget on a Win98 system? 
Pmw generally seems to work ok, but when I try the examples at

they don't run.  I get errors like

Traceback (innermost last):
  File "C:\PROGRA~1\PYTHON\TOOLS\IDLE\", line 131, in
    execfile(filename, mod.__dict__)
  File "C:\Program Files\Python\Bruce\", line 5, in ?
    g = Pmw.Blt.Graph(master)       # make a new graph area
  File "C:\PROGRA~1\PYTHON\Pmw\Pmw_0_~1\lib\", line 260, in
    Tkinter.Widget.__init__(self, master, _graphCommand, cnf, kw)
  File "C:\Program Files\Python\Lib\lib-tk\", line 1084, in
TclError: invalid command name "::blt::graph"

Any ideas?
