Do you have to press save after vts sectors

[flash]

When pressing the get VTS Sector button,do you have to press the save
button after it as done it's thing or will it save automatic?
And do you need to do just one ifo or all of them?

Still getting to grips with this programme but wow! is it great.;)

When you press "get VTS sectors" it will save it automatically, when it asks "do you want to process ALL IFO's", or something like that, press YES and it will do all IFO's, so you won't have to do them all just one.

Cheers...Just that some of the guides around seem to be old and they
say make sure you press the save button.Plus when I have finished with ifoedit it says "Some files have changed do you really want to quit without saving" or something like that.
