Apparently, the WebRoot Firewall is blocking ClipMate from accessing the clipboard, and possibly performing screen captures. Symptoms will be:
1) When capturing text from browsers, the data is not captured. You may end up with clips that have other formats, and are titled with OTHER: and date/time.
2) When performing an area screen capture, the screen turns white.
3) When your browser is in the foreground, you cannot bring ClipMate up with the regular hotkeys Ctrl+Alt+C or Ctrl+Shift+Q.
The solution is to flag ClipMate as "protected" in the "identity shield" setting within WebRoot. (WebRoot support, please correct me if I'm wrong, I'm sure you'll be visiting here soon...)

Many thanks to my customer Ilsa, who spent many hours on this. WebRoot owes her a nice gift card, I think.
