how do i stop clonecd from closing the cd?

nah, that doesn't seem to work, after i burnt an image onto a cd (unchecking that thing), i go into explorer, then properties of the cd, and it says it's got no free space, and if i do 'disc info' with nero, it says there's no free space,..... and finally (this is what i want to be able to do) i want to be able to burn the cd again with another image (multisession) with clonecd (if i do it now, it says cd is not blank)
