[ncl-talk] problem with x11 window

[Rick Brownrigg]

Hi David,

We've heard of at least one other instance of this problem on Ubuntu. As
Alan mentions, it was pervasive under XQuartz for a while, and it was
fundamentally an X11 server issue that was ultimately fixed by the XQuartz
people. Why Ubuntu now, and why not other Linux distros is a huge mystery
at this point. Unfortunately, we don't have access to an Ubuntu machine, so
we don't know if its the same issue as under XQuartz, and thus nor do we
have a patched binary similar to ncl.xq.fix that Alan mentions.

I don't really have a good answer for you. We can perhaps up the priority
on getting an Ubuntu box in place that we can test on.

The ncargex issue is unrelated. If being able to use ncargex is important
to you, let me know.

Rick
