Steps to reproduce:
- From main menu select PLAY ==> SCENARIOS
- Click LEFT MOUSE BUTTON on TEAM PRODUCTION
- Use UP ARROW key to move selection to PVP
- Press ENTER(RETURN)
- Observable behaviour: Selection goes back (after noticeable delay) to TEAM PRODUCTION
- Expected behaviour: Pressing ENTER(RETURN) key is an equivalent to pressing CONFIRM button.
On the other hand load/save menu, multiplayer browser, mods and replay menu works as expected - ENTER confirms selection.
