Welcome to the wonderful world of Captivate.
I have two suggestions:
- Submit an enhancement request so that the preferred DEFAULT capture mode can be set as a preference. (What you're doing above with the Project Preferences: Recording Modes setting is only configuring how that particular Mode will behave. By selecting it in that drop-down you are NOT configuring that mode to be the one selected by default when you do a capture.
- Live with it.
