OO goes to sleep

I've not found an answer to this over the last few versions. For as many versions as I've tried of OOP writer, they all seem to become unresponsive about every 10 minutes or so (not timed exactly, I'm too frustrated at the time). I don't have an internet connection that's open, and it doesn't look like it's waiting for that. It will just not respond for 2-3 minutes+, even on the simplest of docs. I have the backup set at 30 minutes and that didn't change it. No disk activity or increased cpu usage, and windows doesn't report that it's become unresponsive, so it must still be handling messages, just caching them. After 3 minutes or so, all the key strokes happen and it's fine for another short time.

How do I stop this??

Thanks,
