FS9 and FSX. A small belgian developer, Miseo, has just released Track-Shot utility. This program is easy to handle, helps you track your flights and will be continuously enhanced.
Basically, Track-Shot tracks your flight datas (heading, ground speed, true airspeed, fuel and position). But it also generates a screenshot every 30, 60 or 90 sec. For instance, if you want to report some issues in your aircraft, just switch in VC view when the program is ready to capture the view. But you can also keep memories of your flights by catching gorgeous landscapes along your route.
The screenshots quality can be tuned and you can even send them to friends via a FTP server.
There are of course dozens of FS trackers already, but this one is rather cheap (you give a donation of 5 euros minimum) and the developer, who developed it for a virtual airline, will keep improving it.
