I still think it crashes only after a try...last night i set the priority to high and it crashed... so there goes my theory.
although, i did have a few other applications open which was different.
i think the problem is a memory leak in rugby08.exe
i've monitored the memory usage and there's a steady increase, the more games you play in a row the greater the memory usage.
Something I noticed just now is, I just scored a try and in the replay I saw one of my players injured. I quickly pushed exit and replaced the player even before it went to the screen where it prompts you to sub the player.
Once I exchanged him the commentator just said one of the sub lines and it went straight to kicking the conversion.
Now I'm not sure if that player was really injured or just the magic water situation.
I'll see how I get on, whenever I score a try I'll quickly push Exit and see if the Stamina on any of my players are really low then I'll know they're injured.
