Things to set before clicking record :

• Click the SWF button to toggle between AVI or SWF
  AVI can be edited later, using Movie Maker
  SWF creates a web page to display the video
  
  
• Click the Region Menu to get full screen, or to select a region
• Click Options to turn on or off audio recording,
  toggle hiding or showing the cursor...
  I recommend against autopan unless you have a lot of experience... the system tries to follow the action too closely zooming in on the wrong items
  
  
• It is possible to create screen annotations, but these must be done in advance... I recommend using CamStudio simply to capture your screen work, then edit in an external program, such as Movie Maker or Camtasia, if desired.
  
  
• Once you finish recording , you will be prompted to save the file.
