Firstly, this is not a Unity question, I'm a Ubuntu 'Classic'™ user!
What really annoys me is that everytime I open an office document the libre office writer doesn't appear on the current workspace, but on the one on the left or right. I really don't know where this comes from, but it is a really weird behavior as this only happens to libreoffice writer windows, for instance, presentations are not affected.
For example:
I run 4 workspaces which look like this:
+---+---+
| 1 | 2 |
+---+---+
| 3 | 4 |
+---+---+
If nautilus is on workspace 1, libreoffice writer opens on workspace 2 and vice versa.
If nautilus is on workspace 3, libreoffice writer opens on workspace 4 and vice versa.
I did have a look at the compiz config settings manager, but toggling a few plugins did not help.
Thanks in advance!
