Crash, patch and time compression (newbie)

[Jethro13]

Ok, here are a few questions from a new player :

1) Why does my game crash after reloading a saved game ? It brings me back to the desktop after 20 seconds or so, but starting a new game is no problem...any clue ? Does the patch 1.4 fix this ?

2) About the 1.4 patch, does it include every improvement from the previous patches or do I need to dw/load all of them ?

3) Is there any reason not to time compress when on your way to a patrol location ? Someone said it makes you miss enemy planes and such, any value to this ?

Thanks for the help.
