Good afternoon,
As posted to the VNMR buglist:
Mark Miskolzie in the Chemistry department at the University of Alberta found the solution:
To enact this solution on the mac you must go to the X11 and from the preferences select:
Output-> Colors
Reduce the colors until everything starts working again.
I tried 256 and it was fine.
Best wishes, Ryan

Yes, I have seen it before. Color depth is key here. For a linux based
system turn the desktop color depth down to 8 bit and then do X
forwarding through ssh, or run two windows managers - one 24 bit the
other 8 bit (The 8 bit session is for vnmr, the 24 is for regular
desktop usage.), or, best of all, use XDMCP to log into the system (make
sure your firewall(s) is not too restrictive). For X windows on a pc,
set the X windows manager to use 8 bit emulation. I do not have a mac
but I would assume the same ideas hold for a linux based systems. Some
windows managers do better than others displaying vnmr so that maybe be
helpful (i.e. gnome, kde, flux box, etc.) and some graphics
cards/graphics drivers handle this better than others as well. I have
dealt with this since Red Hat 6 (RHEL and Fedoras early predecessor).

Subject: VNMR Broken - Follow up?
Hey All,
I noticed that there was a thread back in september about the spectrum window in VNMR being broken.
Basically there are 3 windows the program uses, and one of them isn't working. It shows all text as black (although it's instructed not to), doesn't refresh properly and doesn't respond to clicks in it.
I'm having the same problem described in that post, and I was wondering if anyone ever found the solution.
Thanks!
Nicolas
Text from old post:
Eh... hmm... this is certainly odd.
What version of X11 were you using before you updated? The only thing that I could really think this might be related to is the alpha channel issue which is present in 2.2.3 (and thus in the 10.5.5 version as well). This was fixed in 2.3.1. Have you tried 2.3.1?
If that doesn't work, I'd recommend removing all traces of X11 from your system: rm -rf /usr/X11 /System/Library/Launch*/org.x.* /Applications/ Utilities/X11.app
Then install X11User.pkg from your Leopard 10.5 DVD. Then install the 2.1.2 update from xquartz.macosforge.org and let me know if that works. That shouldn't be too much different than the versions shipped in 10.5.2, then try updating to 2.1.3, then 2.1.4, then 2.2.0.1, then 2.2.1, then 2.2.3, and tell me which version introduces the problem.

Hello all, I've been merrily using Varian's VNMR remotely via X11 with a solaris box for some time, however, today's 10.5.5 X11 update broke functionality with VNMR. Specifically, there are 3 windows within VNMR, the "menu"/command window, which works just fine, the "spectral" window, wherein directories are navagated and spectra are viewed (which does not work, see below), and the "output" window, where various informations are displayed (Works fine).
The problem here is that VNMR's spectral window, once full of information now remains all black despite any file browsing or spectral viewing activities attempted. I've confirmed that this is an update problem as several people in my lab have updated, while others have not, and universally those who have not updated have no trouble while those who have, always do. I have tried deleting the com.apple.x11 prefs and tried the tricks found in previous x11-users posts:
http://lists.apple.com/archives/x11-users/2005/Jan/msg00093.html (& others from several years ago)
to no avail. I have also tried to downgrade by installing various different X11 versions from the Xquartz site: http://xquartz.macosforge.org/trac/wiki without any luck.
Does anyone know how to solve this vexing problem? I can't seem to find any errors in logfiles or the console anywhere unfortunately.
