@ DaveAz
I had a similar question with the 20270 kitchen. What I've been doing is opening the built-in TaskManager Program and switching to show -> processes. I figured out that it's mostly just the arrows being broken on the dialer I use. (hey, the popup did warn me in the kitchen)

Is it MS Direct Push's schedule in Active Sync.

Did you install any programs that would possibly edit this registry setting?

Lastly, you can check the registry entry for "cachetime" in [HKEY_LOCAL_MACHINE\Comm\ConnMgr\Planner\Settings]. The value is in seconds.
If that doesn't fix it then Schap's advanced config will auto disconnect connections after set # of minutes.
