user7110: Just returned to chess after 40 years (yes I know).  I have a memory of being taught that the kings could not face each other on the same line or column. Chess Titans computer game doesn't seem to recognise this or have I got it wrong.  I understand the rule of Kings not being next to each other but I'm talking about the along a whole column for example

user7020: There's no such rule in chess, king only attacks fields adjacent to him, so there is no valid reason for that situation to be impossible.

user7177: The reason your game doesn't honor this rule is because it is not a rule.
There is some confusion over "facing each other"  If you mean two Kings directly facing each other (where one could theoretically attack the other) then yes, it is an illegal move because one cannot move their King to where it can be attacked; however, if you are talking about "facing across the entire board" in a manner where if a King was a Rook it would be able to attack, then perhaps you have confused chess with one of the older games attributed to it's lineage.
Chinese chess has this rule, and it is part of the common strategy within that game to limit the opposing King's position by placement of your King.  In Chinese Chess, however, the kings cannot leave the palace and the if the opposition is blocked by a piece the other King has more leeway in movement.

user291: No, this rule does not exist in chess.
