I have set my options to lock KeepPass 2 after a set amount of inactivity for both KeePass 2 application as well as my computer. It works fine when I am looking at a list of entries. Inactive for the set amount of time and it locks blanking out Keep Pass 2 UI and I need to login again. Great. But, if I have an entry open it does not work. IOW, I double click an entry and the popup opens with the details of that entry. I leave it open and it will never lock. I've left it open for way past the set timeout time and it remains unlocked.

Using the forum search would show you that this behaviour has already been discussed
and will not be changed.
The explanation for why KeePass does not lock when a sub-dialog (e.g. Edit Entry dialog) is open is provided at http://www.keepass.info/help/base/faq_tech.html#noautolock.
