Ok folks , In my following game I have come accross a big problem with Crashes :-
Civ (or rather ptw) seems to crash when it get's 'overloaded', as I have only a modest PC that is often when I do something daring like enter diplomacy

, the sound will go all choppy and eventually crash
There seems to be a problem with my HD, when I play civ I go in with literally hundreds of Megabytes free on my disk, but after the crash there is typically 1 or 2 megs to spare - clearly nothing. I have a suspicion this is something to do with Virtual memory?!
In any case, how do i avoid this problem??
Cheers
Matt
