Problems with Office Plug-In's

When I activate Greenshot and select an area on the screen to capture the popup menu appears. If my mouse cursor hovers over the MS Office apps, eg OneNote. Greenshot attempts to open OneNote. Since I do not use this application Greenshot hangs. Basically if the mouse cursor wanders over some parts of the popup menu one can hang OneNote. I've tried to disable the interfaces to the MS Office apps. Unfortunately I can still hang Greenshot by accident.
