Infrarecorder CD copy method

I was posting at the sourceforge.net help page and a user suggested I as here for help because there is no help over there.

I find the copy method strange, is this correct or am I doing something wrong? I am coping with source and target the same drive. I insert the source first and I cannot seem to get the copy disk option to work. But, if I insert my target disk first I am prompted to insert the source disk and it seems to work fine is that normal?
