Thank you Daniel.

Clicking on either list view or detail view once or twice just brings
it or from one to another. Right clicking on the directory doesn't
allow me to do anything.

Clicking on list vies does show **two** columns in the window. However,
the individual, single files are the first, at the top, instead of
under the directories. Which have always been on the top.

The detail view delivers a single column, the individual files are still
shown at the top instead of below the directories.

Ce la vie. I think I will just have to live with it.

Thank you for your suggestions.

Stay well,
Charlie

Others can perhaps chime in on this, but I think the issue has to do
with what theorem environments are defined in the various
theorem*.module files. Certainly if your collaborators used the theorem
definitions from those files, then all would be well; and it may be that
you could define your own module, with whatever definitions your friends
use, and that would work. But I don't know.

Unfortunately, there's no way that tex2lyx can understand arbitrary
constructs, so we will always be limited somehow. People using LaTeX
will sometimes do things like:

\def\begq{\begin{quote}}
\def\endq{\end{quote}}

We can't possibly figure that out in the tex2lyx code.

The truth is that even exporting a LyX file to LaTeX and then
re-importing that same file (what we call "roundtrip") won't always give
you the same file back again. It's a goal to have this work, but even
then it is not easy. So, in all honestly, we would not advertise that
LyX allows one to collaborate with someone using raw LaTeX. We even
discourage trying to collaborate with someone using a different major
version, e.g., 2.2.x vs 2.3.x, largely for the same sort of reason: the
need to use ERT to handle new constructs in the lower version.

All that said, improving tex2lyx is always a goal, so specific bug
reports are always welcome.

+1 we would all love for LyX to seamlessly import LaTeX, but it is just
way too complicated of an issue. I also recommend that when
collaborating, you should use the same set of tools. Although LyX
exports LaTeX, it is not a LaTeX editor.

As Riki mentioned, there are continued improvements. see the "tex2lyx"
section of the following for recent improvements that will be in LyX's
2.3.1 release:

Jürgen and Riki -

Thanks. I will try to file the bug report.

Is there a place were one can read the requirements for a LaTex file to import 
correctly? For instance most files I receive from collaborators do not have the 
theorem definitions in the right form.

I think LyX is a great tool, both for learning LaTex and doing serious writing. 
However none of my 70 coauthors have used it, and except for my current 
students, I know of nobody in my department who uses it. I think the greatest 
obstacle to wider use is that Tex2LyX does not work reliably. By the nature of 
the task, Tex2LyX is trying to convert files that were not written for LyX, so 
requiring special forms of LaTex devalues the program.  When I collaborate I 
end up using LaTex instead of LyX most of the time or using LyX to create LaTex 
segments to cut and paste. One of the first big advantages of LyX is that you 
get structure for your document with numbered theorems, etc. It would be nice 
for demonstration/advertising purposes if this always worked.

I realize I was not very precise. I'm attaching a screenshot of my LyX
dialog; not sure it will work so let me describe as well.

The last 2 icons (before "Documents" and "Examples" are "list view" and
"detailed view" (I do my best to translate from French).

I suggest that you select the latter. Then you end up with an
explorer-like windows, where the columns have titles "name", "size",
"type" and so on. These are clickable. A small arrow (up or down) next
to one column shows how the files and folders are sorted.

Try clicking on the "name" or "type", once or twice. If I do that, I get
precisely what you describe, but then a 2nd click restores the
"directory first" sort order.

Thanks Daniel,

Can't find "sort by type".

Using LyX Version 2.2.2 Qt Version (run-time): 5.7.1 Qt Version
(compile-time): 5.7.1

on

Linux 4.9.0-6-amd64 #1 SMP Debian 4.9.88-1+deb9u1 (2018-05-07)
x86_64 GNU/Linux

Using fvwm.

The file manager does not have this problem with the directories

There is another thing not working with LyX as well and has been so for
many months. That being the scroll bar is not seen till F7 is pressed
for spell checking, then the scroll bar appears and remains.

Will probably just have to live with these things.

Thank you for your reply,
Charlie

One problem is that the theorems are named and defined differently to
those LyX supports ("theorem" and "corollary" vs. "thm" and "cor"), and
see

https://www.lyx.org/trac/ticket/10432

If I change that, it sill does not import for me, so there must be
another issue.

The following does not look good in you example (mismatch in begin/end).
