I've only had it freeze up once, when rapidly deleting books from a collection without waiting for the screen to refresh, so this hasn't been a problem for me.

I understand it is happening on periodicals. When I was looking at the BOOKS.DB awhile ago I noticed there is a very complex view that is created for periodicals and maybe it has something to do with not enough memory or a memory leak in that case. That doesn't explain the problem with books however.

Since it has been working perfectly for me I wonder if it has anything to do with DRM books since I don't have any. I read mainly epubs with an occasional PDF now and then.

So when anyone experiences a problem it might be useful if they can say if the books has DRM or not. It may have nothing to do with DRM per se, just that it might take more processing/and or memory.

Also since users are experiencing the problem after reading for a while that may indicate a memory leak in the OS. So a shut down or reset would free up the memory.

Again I haven't had a single problem with reading and I use page swipes 99.999% of the time. I also have WiFi turned off unless I'm using the browser, maybe that makes a difference.
