unload memory when game is over

Hi,
The quickest route will be just to reboot, but if that's not an option try the free maxmem utility -

(remove any spaces from that url)

Which will reclaim memory as to the settings you provide (IE set it up toaggressive and it will clear out just about everything that you've opened since boot). I use it on my XP machine, and have had no problems with it at all. Funnily enough, we often have a quick game during the lunch break here, and I run it before playing to free up memory and improve performance for the game itself. I also use task manager to kill explorer, which free's up a few MB's for gameplay. Rather than close the game, restart explorer and then run maxmem I personally find it easier just to restart my laptop. hope this helps...
