If you stick with 6.5, you will have problems when installing 32bit
libraries because they only keep the latest version, so yum forces you
to upgrade existing 64bit libraries to the newest as well to match with
32bit libraries. So, it is kind of frustrating. I just found that new
X11 does not correctly support double buffering with Tk. Hopefully, I
can resolve this problem soon. People may run Virtual Machines in the
servers for while until the fix is released.

Hi,
Happened to me on Monday after yum update. Seems CentOS 6.7 is out
and as many as 400+ packages were updated. I am sorry but I did not
make note of yum history. I suspect the X server gets updated and
cause this problem. I fooled around trying to roll-over but that did
not work.
Then I decided to upgrade to CentOS 7. Please do not try the in-place
upgrade! It broke my system. I finally made a DVD install. Sparky runs
in CentOS 7 but many old software wont. No 32-bit support in CentOS
7. May be there is a work around but I decided to downgrade to
original CentOS 6.5. It seems things are back to normal although the
newly installed NMRFAM Sparky comes with a blue background. Never ran
it before and have only seen brown or gray colors for old sparky.
People on CentOS and related Linux may want to hold on with update
till this issue is nailed.
Best regards

Hi,

You may be using Scientific Linux 6 that is built on RHEL 6.
I am trying to figure out what is going on, but it is more likely
faulty
X11 libraries shipped out with RHEL, and in that case, it will not
be a
easy fix. I will report if I can find a way to fix this problem.

Hi,

I seem to have the same problem with sparky.
On my machine sparky stopped displaying the spectra, just like in
the
attachment earlier
in this thread.The contour panel on the right still works as well
as
the trace (vS)
l
It was working fine before the weekend and Im not aware of having
changed
anything to the system or in userspace. Im not doing automatic
updates.

Its an old version of sparky 3.110 that has worked fine for a
long
time. .
If I try the new NMRFAM sparky the result is the same.

Im on scientific linux.
