JFYI, I have left RTW and even more intensive games like Far Cry running for hours, even a few days; often minimized even.

I didn't know it could run out if left it idle but not if I play hehe
Yeah, its called "Memory Leak". Completely the fault of poor programming. Which is not to say that CA is guilty (or not guilty). The issue could lie anywhere even with Microsoft. Windows used to be NOTORIOUS re memory leaking. Generally, just as a kinda guide, the longer you leave programs *open* the more susceptible (sp?) they can be to memory leaking. Though, as I said is all on the programmer(s), some do a great job, some poor.

Additionally, LOTS of *weird* things WILL happen, such as you describe, if a system has less than **quality** parts. The quality of the memory that the MAJORITY of most people have in their systems is poor. Quality memory is not cheap!

I can keep my system going, because I'm *anal* and very particular about the parts I choose for my system. Which is not to say it runs perfectly, just that certain things aren't an issue for me. I run my system 24/7 so I try to compensate for things like memory leak.

One way is I use a program consistently running in the program called "Cacheman". This is a great program I've used for YEARS! I reccommened it, particularly if you don't have a lot of memory. These days 1 gig is pretty much the norm for smooth *gaming* operation; and, soon 2 gigs will be necessary. I also suggest it, if you have less than top quality memory--helps a LOT!

WindowsXP is *supposed* to do a better job managing memory, and it certain ways its does, but it other ways it doesn't. Frankly, IMO, its better *still* NOT to allow Windows to manage your memory, but that's another discussion.

I think I know what happened though. I think the screensaver started up and RTW's reaction was to quit to title screen or something.
Sounds like a good bet.

RTW was taking all the memory space, and the SS pops up says to RTW move over I need some space. RTW says whaaaa??? SS says Yeah, you don't need all that space, take some of your stuff and move it to the Paging File. RTW says whaaa?? SS says, screw it, move over I'm coming in---Shove! RTW goes Crash!

That's a VERY general and layman's way of looking at it. If you don't have a lot of memory, I'm certain that RTW will take not only most of your memory space, but also most of the paging file.

You'll notice that there are two versions. CachemanXP is for guess what XP; and, Cacheman if for Win2000. Though, Win2000 users can still use the XP version. The interface is different and some things have been updated in the XP version. I continue to use the Win2000 version cause I too lazy to upgrade, and why fix what ain't broke!!

Luck!
