Software simulation not recording "hover" buttons.

Captivate doesn't always 'hear' changes on screen with some apps or web applications.  That means you need to do a manual capture of any changes that don't get automatically recorded.  If you don't hear the camera shutter sound at some point when performing a capture session, but you WANT to capture that change in a separate screen, then you just need to hit whatever key you have assigned for those manual captures.

By default it is the PrintScreen key, but since I am right handed using the mouse, I prefer to change the setting to the F2 key so that I can navigate the software interface with my right hand while my left hand hovers over the manual capture key just in case I need to pick up another capture manually at any point.
