I'm posting back some results of my 1 thousand tests just in case someone could help me...

At first, I thought that it was a problem related to versions of office but I have asked some colleagues to open and run the macros and send back the file to the person with word 2010 and for some reasons, one computer with word 2007 is working and another with 2007 doesn't work...

After that, I found out that if I open and save the file with my word 2013 the person with word 2010 won't be able to use the macros (the macros seams to be disable, we can click on the button but nothing happens, no VBA is running. But if a person with word 2007 (the version that work) open and save the same file I have opened earlier (with my 2013 version), the person with word 2010 will be able to open the file and all the macros will work correctly... It seems to reactivate the macros that were disable in the 2013 or the 2007...

any ideas of the source of this matter...

Thanks in advance for your kind help...
