The mini-map for the first mission of the Federation campaign will only appear if I hover my mouse over it. This is not an issue in skirmish, only the campaign. Difficult to make full use of the mini-map if I can't see it all the time. Is this a known issue?

Its a feature. Hitting CTRL+F1 hides the minimap with on hover popup. Alternatively ALT+F1 will hide it completely with no popup.
