Playback starts several measures earlier than I click

Hi,

It sounds like you are using Alt-Space to initiate playback, which puts Composer in Practice mode. Plain old Spacebar starts normal playback.

In Practice mode, Composer will play a "n" bar lead-in (depending on the settings) and will loop between marks that you can specify.

Look at the Perform-Practice Setup menu item to see whether that's the case.

Hope that helps.
