Alejandro,
That's a separate bug, not caused by Emerald. There are other issues where windows don't respond when they have been minimized. You have to shade them to the titlebar and restore them to fix window mapping for it.
See https://bugs.launchpad.net/ubuntu/+source/unity/+bug/754065 for it. Might be related to what you have.
