 NVIZ fails to start in any of the four GRASS versions on my computer.
 Running Fedora 10, kernel 2.6.27.12-170.2.5.fc10.i686. I have GRASS-6.2.0
 (compiled by me), GRASS-6.2.3 (compiled by me), GRASS-6.4.0-RC3 (compiled
 by me) and GRASS-6.3.0-6.fc10 (installed from repository). All were
 compiled/installed on 29 January 2009 with the OS updated as at that date,
 using defaults for compiling. NVIZ in GRASS-6.0.2, GRASS-6.2.3 and
 GRASS-6.4.0-RC1 ran fine in Fedora Core 5 back in December 2008 and/or
 early January 2009. I upgraded from FC-5 to Fedora 10 (clean OS install)
 on 26 January 2009. NVIZ failure to start noticed today, with all
 available updates and bug fixes as at 3:00 pm Atlantic Time on 03 March
 2009.

 When running GRASS-6.2.0 and GRASS-6.2.3 by clicking the icon on the
 display window, NVIZ stops at the tiny grey NVIZ screen plus tiny black
 screen with red "please wait" (both stay up until I close the tiny
 windows). Running NVIZ from the command line I get the following messages
 for GRASS-6.2.0 and GRASS-6.2.3 respectively:

 --snip--
 Loading data
 translating colors from fp
 Update elev null mask
 Loading data
 --snip--

 and

 --snip--
 ading data
 Update elev null mask
 Loading data
 translating colors from fp
 --snip--

 When running NVIZ from GRASS-6.3.0-6.fc10 or from GRASS-6.4.0-RC3 by
 clicking the display icons, the tiny NVIZ windows quickly flash on and
 off.

 When trying to run NVIZ from the pull-down menu in GRASS-6.3.0 I get this
 error:

 --snip--
 nviz elevation=Site_plan_elevation3 at Ocean_Links
 Loading Data

 translating colors from fp


 Update elev null mask

 Error in startup script: could not create rendering context
     while executing
 "togl .middle.draw.canvas -rgba true -double true -depth true"
     (procedure "Nv_makeGUI" line 56)
     invoked from within
 "Nv_makeGUI .top"
     (file "/usr/lib/grass-6.3.0/etc/nviz2.2/scripts/nviz2.2_script" line
 1045)
 --snip--


 When trying to run NVIZ from the pull-down menu in GRASS-6.4.0-RC3 (either
 from tcltk or the wxpython GUI) I get this error:

 --snip--
 nviz elevation=Site_plan_elevation3 at Ocean_Links
 Loading raster map <Site_plan_elevation3 at Ocean_Links>...

 Translating colors from raster map <Site_plan_elevation3 at Ocean_Links>...

 Loading raster map <Site_plan_elevation3 at Ocean_Links>...

 Error in startup script: could not create rendering context
     while executing
 "togl $Nv_(TOP).canvas -rgba true -double true -depth true"
     (procedure "Nv_makeGUI" line 56)
     invoked from within
 "Nv_makeGUI $Nv_(AREA)"
     (file "/usr/local/grass-6.4.0RC3/etc/nviz2.2/scripts/nviz2.2_script"
 line 1052)
 --snip--

 I have also run NVIZ in earlier versions of GRASS on Fedora Core 5 and
 FC-2 machines, as well as as on Red Hat 7 and 9 machines, all with
 success. The error messages above seem to suggest script issues (??),
 unless there is a call somewhere that is Fedora 10 specific? One of the
 bug upgrades applied via Fedora repository today was to tk libraries.
 Can't tell whether this is the cause of the problem, however, as I have
 not run NVIZ since upgrading to Fedora 10 in January.

 Hope this information is useful. Beyond this, I'm at a loss, and cannot
 think of anything else to add.

 Regards,
 Rick

 P.S. Grass Team, you have done and continue to do a wonderful job :-)
