Hi, I'm on windows 10 and windows crash when I click on libreoffice files,
the crash is related to a corrupted lock file that I found in c:\..something
in user folder..\roaming\libreoffice\4 and deleted it, it worked but it
happened again with another file, is there an ultimate solution to this
bug??
manythanks, ciao, Pier
Which file did you delete ?
(complete name, and not '... something in user folder...' ) you can replace 'Pier' with '<username>' ) . 
This link tells you what to do if you have a corrupt user-profile:
LibreOffice user profile - The Document Foundation Wiki
<https://wiki.documentfoundation.org/UserProfile#Resolving_corruption>
( https://wiki.documentfoundation.org/UserProfile#Resolving_corruption )
Please try to get a new user-profile, and see if you can reproduce the problem....
