I have some strange behaviors with MOI 3.1 on OS X. I am using an iMac 5K late 2015 in its highest configuration with two extra monitors.

When pushing the Moi window to one of the extra monitors and then go to full screen mode with Moi, the Moi window sometimes disappears.

When trying to export something, often the export-window is under the Moi main window but I am unable to bring the export windows to the front.
