I've recently upgraded to Flash CS4. However, the project I'm currently working on was started in CS3 and I need to keep it as a CS3 as I transfer the .fla file between two computers because one only has Flash CS3.
Is there way of setting it so when I click 'Save' or Ctrl+S it saves it automatically as a CS3 fla, rather than automatically converting it from a CS3 to CS4 file?
I'm serial Ctrl+S hitter so this is getting really annoying now having to go to File>Save As everytime!
I don't know of a way to reset the preferences to defaultto saving as CS3, but what you can most likely do is save the file without concern for it being a CS4 file, then save it once as a CS3 file when the time comes to need it on the other machine.
