Yes, I can't get a frame border either. Thanks for translating the options.

There are (Very Good) bwidget instructions and demo.tcl in the GRASS 5
source code. (hopefully you found them?)

[should we copy into GRASS 6 lib/external/bwidget?
 252K    demo/
 368K    BWman/
]

cd grass-5.4.0/src/libes/bwidget/demo/
wish demo.tcl

in the demo the LabelFrames borders work correctly, so I think it is
something we are overlooking (???).

I do want to replace it for 6.2,

As it works in demo/demo.tcl, I think it's a fixable bug on our behalf.
( somewhere :-/  window parent/child relationship? lack of content?)

.. but but but .. are there bwidget replacements for those we can use?

=== (lib/external/bwidget/README.grass) ========
only requires 2 lines of code in your Tcl/Tk script to use the new widgets.
Some of the new widgets include

    On mouse over help balloons
    Tabbed notebook panes - like worksheets in Excel
    Directory tree listing
    Combination box or drop down option list
    Progress bar
    Many others
================================================

seems to me that there should be replacements, and we don't (really)
have to worry about finding any we don't know about until we get an
error report. And then it's a (hopefully) quick fix. We are pretty
sure this is the only v.digit problem, and pretty sure that d.m is ok
(so I'm not as worried about gis.m).

works for me (besides missing border). I expect it will work on all
platforms (I can't see why it wouldn't).

An immediate solution: adding "-background HoneyDew" makes the
"-relief groove -borderwidth 1" failure less important.
