After upgrading to the last version (31.6.00); I cannot open .doc files. I use Open Office 4.1.1. No problem with .xls or .pdf files. But neither the attachments in my sent mails nor the attachments in incoming mails type .doc can be opened by clicking on them. I have to first save to the computer than open the file which takes too much time. In the attachment you can see the error message. Here is the translation of the message: - Top window: File cannot be saved as an unknown error occured. Please retry. - Second window - below filename: Error - source mailbox
