Reviewing through your description, there are a few options available which should open links into a new tab/window. By default the Jive platform does not force users to open content in new windows, however you should be able to use your Mac or Windows hotkey combinations to open a link in a new tab/window:
- ctrl + click
- middle click
- right click >> open in new window/tab
Let me know if this resolves the issue or you have any additional questions.
Jesse, can Jive platform (8.0) force a user to open content in a new window? Is this something under the admin-console?
