It is possible the computer you (or boss) are using does not
have sufficient resources for what you are attempting to do.
It is also possible that you are shutting down
not because of Captivate, but
because you are "clicking" something on the target
application that is causing the system to lock up.
It is also possible that the machine has another program in
memory that is conflicting with Captivate's efforts to log
keystrokes. This may be something that you or the boss uses
regularly and knows about, or it could be something as insidious as
"malware" that should be removed from the computer system (by a
malware program like PCTools "Spyware Doctor").
This last is kind of a duplication of my first suggestion,
but it is possible you or the boss are creating movies that are too
large for your development machine to handle - too large can mean
in pixels, or as in too many screen background captures. Remember,
Captivate demands a lot for audio and for video.
Suggestion: Try turning off all "automatic" capture features,
and see if you have more success just pressing the PrtScr key when
you want a background captured. In other words, in the "Recording"
dialog, turn off "Enable Auto-recording", as well as "Automatically
use full motion capture for drag and drop actions" (from the "Full
Motion Recording" tab). That experiment might tell you more about
where the problem is . . .
Have a nice day!
