Overview: Opening a file twice in quick succession results in 2 read/write windows of the same document. A customer of ours has a hyperlink on a website, which triggers a script that opens a document with the 'soffice' command. The users often double-klick on this link, which results in this problem. Steps to Reproduce: 1) Open the same file with "soffice <document.odt>" command twice. Alternatively you can use the following command to emulate this: "soffice <document.odt> & soffice <document.odt>" Actual Results: Two windows editing the same file open. Expected Results: One window opens editing the file. The second command doesn't open a new window but instead sets the window focus to the first window. Build Date & Hardware: V6.1.6.3 release 3 on RHEL7 Additional Builds and Platforms: Also reproduced on: Ubuntu 20.04 V6.4.2.2 6.4.2-0ubuntu3 and on Mac OS with Libreoffice 6 (exact version unknown)
Implied here is that if there is a delay so that the document is actually already opened before the second instance is started, then it works as expected. And I can confirm that. It sounds like NOTOURBUG to me.
I'm going to assume this is bug 137356, please try with version 7.1, which contains the fix, and reset status to UNCONFIRMED if the bug still occurs. *** This bug has been marked as a duplicate of bug 137356 ***
