Simple character menu bug and fix suggestion

Notice this issue when sending employees on vaca. While the menu is rolling back up from selecting Vacation option, I can quickly select another option (research/train) for that employee before the menu leaves. I usually hit it while trying to select a second employee. Not the biggest of deals and hard to find, but just adds a bit of polish. Maybe just send the menu into the background while it’s rolling up and bring it back to foreground on display?
