threads showing as already read


pretty much at least once a day all threads are showing as already having been read by me. I thought it might have something to do with switching from my laptop to my phone. But tonight I opened the forums with lots of threads showing new posts. Every one that I opened went to the latest post (the post made after the last post i had read in that thread.) But I have had the forums open on my laptop for about 3 hours or so now. I went to different tabs for a while and to other programs and now when I come back and refresh the forums all threads are showing as read already.
any ideas why this happens and how to stop it?
There is no way to stop this beyond being active every 29 minutes and 59 seconds to prevent the 30 minute timer from expiring and setting all prior posts as read.

What is the reason for having the software do this? Seems pretty lame to me. I read a different vB forum that i'm pretty sure is much larger than this one and they don't do this.
thanks.
vBulletin is very customizable. There are most certainly sites that use different configurations. Some sites likely use the database tracking to track what a member has actually read or not. The issue is there is significant enough overhead with those settings that it's outlined in the manual with a caution about resource usage.
