It is of course my job to reproduce it (and explain how-to).  Thanks for your consideration.

Hi Francois and Andreas,

On Francois' first question, I wonder if Francois is using attrib1, attrib2... as the actual attribute names in the config file.  If this is the case, Francois, you can name attributes with suitable names in the configuration file and dictate which ones appear in the List and Threaded display modes. In the List Display, those names appear along the top row at the top of each column, which I think is what you want. 

This example of three lines in a config file (made up).

Attributes = Worker, System, Organisation, Customer, Status, Ticket

List display = ID, Date, Organisation, Customer, Worker, System, Status, Ticket

Thread display = $Ticket: $Worker. $Organisation / $Customer, ($message id).

In list display, those words ("Organisation", "Customer" etc) are those that appear at the top of each column.  In Thread Display, note how you can use punctuation.  Also (not shown here) you can colour the line in Thread Display depending on the attribute System (which is akin to your question on cell style colouring) a feature not much used in this forum, and the Icon at the beginning of the line depending on the attribute Status. 

This is in the documentation, but perhaps it's not clear to all that - apart from the system defined attributes - any word can be used as an attribute name, and that "attrib1" "attrib2" is just shorthand for "any words you wish to use as attribute names".

Otherwise, if you want a different word along the top if the column in the List Display (and also in the form for making a new entry) for the attribute that appears in that column, why not just use that different word as the name for the attribute?

On the third point, about Cell Style, it would be good for having attrubute 2 able to dictate the colour of the cell of attribute 1, and no need to show attribute 2 in the List Display.  But take your point that it can be done in a shell script.

I only saw Andreas' edited version of the original enquiry, so I didn't see the orignal config file under discussion - so most of my previous entry is totally pointless.  Sorry about that.

Indeed there was a bug when you have "Show Text = 0". I fixed that in the current GIT version. I also hide the "Preview" button if "Show text = 0" since it really makes no sense there. I made a Windows Patch 3.1.0-3 which  ontains this fix.

Wow !!! Im impressed :):):) I didn't expect such a fast reply !!!

Thanks alot Stefan, I will try it right away !!

Andreas, I really like the idea of hiding attrib 1 and attrib2 and fill attrib3 with a script (I guess using elog.exe command line) ?
I play a little with it and I can modify an attribute with the command line but I cant figure how to set the cell style based on the attrib2 and 
replace attrib3 value with attrib1 value... (basicially I need help !!!) do you think you could help me ?
