[it-users] libreoffice - Internet Explorer impossible to open ODx document from web pages

Dear all , I can't open from any web pages (https or http) any link to a 
ODT/ODS/ODP document using IE8 , IE11 on windows platform running Win7 
PRO sp1 32bit or Win 7 enterprise 64bit , XP pro sp3.
This happens for example trying to open a libreoffice documentation to 
the page https://www.libreoffice.org/get-help/documentation/ or any 
other link found on google that address ODx documents.
When I click on it I got a popup asking to open or save the file. If I 
try to open it (without any Libreoffice app opened) but in this case 
apparently nothing happens. If I lool at the programm running I can see 
that 2 Libreoffice process are opened when I click on the web link. I 
can then open manually LO , use it but I can't close it until I close 
the IE blank windows left after pressing on OPEN popup.
Nothing change if I set LO to stay opened at the startup in background 
nor if I try to open the link with the LO application already opened.
I had the same issue on several PC using different version of LO 4.x 
(verified on 4.1.0.4 , 4.1.2.3 , 4.1.4.1 , 4.1.5.2 , 4.2.0.4)
No issue if I use another browser (firefox,chrome,opera) or if I install 
(standard setup) Openoffice 4.0.1 , it work immediately , and when I 
uninstall OO and reinstall LO again the same issue.
Anybody else experienced this kind of issue ?
Can I do some other check to better identify where the problem could be 
and possibly solve it ?
thanks in advance
Gianmarco.
