#1 clipboard stops notifying listener

[::endless mike::]

Overview:
On rare occasions, the Cache seems to stop
recording Clipboard entries after running for an
hour/day/week. Everything else runs as normal, but it
stops recording new clipboard entries.

Short term solution:
If, by chance, you do encounter this, simply Reset
the service from the system tray to return to normal
operation.

Possible Solutions:
-Trace execution for unhandled error states in the
clipboard listener thread.
-Clipboard listener thread may not be handling an
API error state with grace.
-Implement some watcher to reset the clipboard
listener thread when it stops responding to clipboard
callbacks.
