Backplotter not working with BDI

[John Guenther <jguenthe-at-nafis.fp.trw.com>]

Hi everyone,

I can't seem to get the backplotter, tkbackplot.tcl, to work with the
BDI installed version of EMC.  All I get is a small window, about 2
inches square, in the upper right corner of the screen.  This window has
a white background and nothing else displayed.

The file tkbackplot exists in the plat/linux_2_2_18/bin and tcl/scripts/
directories, it has execute permission but does not appear to be
working,

There are no error messages displayed and tkemc continues merrily on
it's way processing what ever g-code is fed to it just as if you had
never asked for the backplotter to be active.

Any help will be appreciated.

Thanks in advance
