rod03801: If you have a game with time remaining in the red (i.e. less than an hour left), I suggest the following:

1) Open up the game.

2) Check the time limit per move. Let's say that in this case it is 2 days.

3) Check when your last move was made. This should be under your name on the board and say something like "Last move: 25. September 2011, 10:59:24".

4) Add the time per move to that time listed under step 3. In this case, add 48 hours.

5) If the time under step 4 is in the future, you haven't used vacation time in that game.

6) If the game you just checked has for example 15 minutes left, and you have another game that has a time left per move that is less than 75 minutes, you should check that game too under steps 1-5. The reason is that it may already have gone into vacation time and had 1 hour added to time left to move.

All of the above should also take into account weekend time. Fischer clocks make things even more complicated if they add extra hours for each move made. Good luck in that case....
