I have tracked down the cause of this. It's related to a bug where games with no moves were showing the incorrect move time remaining. The underlying issue had already been resolved.
You can still see other players' games. Click on the player whose games you would like to see and it will take you to their details page. Just above the profile box there is a bolded option to "view players games".
Hope this helps, jayjay.
Belated thanks for the upgrade Stoney, much appreciated.
