Re: strange bouncing of EMails

2017-01-24 Thread Dr Eberhard Lisse
To me these look like bounce messages which should go to the list-admin
if that was possible tho they can be removed from the list :-)-O

I am not getting these though :-)-O

I don't have Finnish (can someone who does contact the correct new
address of the two offered perhaps?), but the second one looks like
they don't like fli.bund.de any longer and want to be called fli.de, so
maybe Eildert must unsubscribe the old address and resubscribe under
the new (which is why he reads in copy)

What I do when I get a stubborn mail program, is to create a filter
that moves the file into my bounce folder.

Re: opening the same file in two different tabs

2017-01-24 Thread gordon cooper

 Had not thought about a New Window, I have been saving
the file with slightly different name, so that lyx does not
recognise it for a second tab.  Guess that one needs plenty
of disk room for this - I do have that on the elderly desktop.

Re: Change bar

2017-01-24 Thread gordon cooper

Dear Gunter,
   You have given me a guide as to the possible error.
Providing a minimum example is difficult as there is no error report
provided, so the problem could be anywhere. and I am not aware of
any non-standard settings.  This document is a User Manual with
many images and hyperlinks.

So, my next step will be to isolate the fault, using the old slow method
of halving, testing, then halving again etc., and hoping I can see it in
the source pane.  Will report progress.

Many thanks,
Gordon.

produced by exporting to pdflatex, are generated in a few minutes.
Add the Change bar module and the crashes return.

This looks very much like an incompatibility between the change bar latex
package and some of the other settings/packages you use.

Could you please send a *minimal example* (take a failing document and
remove every non-standard setting and every content that does not trigger
the error).


Have read through everything that seemed related in the User List
Archive, but no clues found.

Another good search point is the LyX bug tracker
https://www.lyx.org/trac/wiki/BugTrackerHome
but in this case the only "change bar ticket" is not relevant.

Sometimes also trackexchange or a generic internet search helps.

  For fine tuning the clipping adjust the above this way:

  If you click 'Apply' when the image is first loaded you get a second

  2.  With cursor within the image, right click and select 'settings.'

In the old days, I believe custom bindings had to be in the same bind file

adds anything it finds in ~/.lyx/bind/user.bind to the standard bindings.
You're not supposed to edit user.bind manually, either; it gets generated
automatically by LyX.

  I was not aware of this. The 'call newframe' shortcut is in user-bind.


You're not near Washington D.C., are you? The laws of, well, pretty much

  No. Portland, OR, area. I stay as far away from that swamp as I can.


Two things to check (after making sure the binding is in user.bind).
First, if you go into Tools > Preferences and search for ctrl+alt+return,
do you see the binding (in bold face) listed? If not, there's a problem
with LyX finding the user.bind file.


  Yes, it's in there.

If yes, open a Beamer file (making sure it's not read-only), park your cursor 
someplace where it would not be horribly illegal to start a new frame, use 
alt-x to open the command buffer, type 'call newframe' in it (no quotes) and 
whack return. If that starts a new frame, at least LyX is understanding the 
command. If not, something truly weird is happening.


  Well, we identified the problem: something truly weird is happening.

Besides the fact that I fail to see what this has to do with LyX, I
have been using that particular package for many years (predominantly
on the Mac but also on Windows (and even on Linux)) and am not only as
happy with it as Prof Knuth, but also found them to be extremely
responsive to constructive criticism.

They offer a free version for download which is identical but prints
watermarks, so one wonders if one should not have tested this before,
never mind a charge back.

How did you specify the backup directory?

Yes

What is wrong with this file name? In the end it is backup only, not meant for

The issue is that it doesn’t save the original file.

The documentation and technical specification guaranteed exactly was I

Fully convinced by what was stated I purchased the license to use

This looks very much like an incompatibility between the change bar latex
package and some of the other settings/packages you use.

Could you please send a *minimal example* (take a failing document and
remove every non-standard setting and every content that does not trigger
the error).

Another good search point is the LyX bug tracker
https://www.lyx.org/trac/wiki/BugTrackerHome
but in this case the only "change bar ticket" is not relevant.

Sometimes also trackexchange or a generic internet search helps.
