Yeah the fish hear us, but must not bother them as they like to stay next to our equipment.  One system we made could even tell what type of fish were schooling around the transducer.  Cool stuff, but not easy to explain. 

I had a choice between Camtasia Studio and Captivate.  So far I am happy with Captivate - you can choose between recording video (it gets everything like a movie) or it can create a slide every time you click something.  The nice part is it automatically enters all the text blocks for you.  If you click File, properties, it recorders the mouse movement, adds the "click the File menu", and then another text box for "click Properties".  Since a lot of our software has very long menu structures, that feature alone made me choose Captivate...  The only problem is with audio - I have chronic asthma.  I cough all the time.  No way can I record anything.
