Under the apple menu, select 'Force Quit Application.' (Use the Force!)

This brings up a window showing open applications, and allows you to switch between them.

You can minimize each application to see if a window, likely a dialogue box, is hiding behind something on the screen.

Just keep in mind that this is your last hope, like Obi-wan. It will force quit applications with warning, but if you confirm it will quit without any option to save data.

I have run into this a few times during recording sessions, so I'll ask: how are you ending the recording session?

Cmd-Tab will switch between applications, and ESCape is supposed to quit recording. Both of these can end a recording session, depending on the initial settings of Captivate when you began the session.

Sometimes I've had Captivate not respond to the ESC key, so I had to Cmd-Tab to Captivate for it cancel recording. If you've done a long recording session, it can take a while for the computer to process the footage and display the Captivate editing screen.

Which version do you use? Are you launching Captivate as administrator? Do you clear the cache regularly? Indeed, look 'behind' the Captivate window to search a hidden dialog box. Or did you ever use two monitors and now switched to one?
