cookie limit

Has anyone else noticed the "limit" on the (I think) trac_topics cookie here on the boonex forum that only holds like 30-40 topics and then I suppose reaches the limit and simply stops tracking them? (marking them read/unread)

At that point I have found that it is necessary to delete the cookie and start over which results in ALL topics being once again marked as read.

This IMHO needs to be increased significantly  .....
