Please, someone, WHAT THE HELL IS GOING ON WITH MY CD RECORDER?

(Cross-posted to the Computerhelp community, which has however been rather deaad and unhelpful of late.)

For years I have recorded files from computer to CD-R, happily and without any trouble, by either dragging their icons on to the CD-R's window or ordering "move this file to" the CD rewriter. Now, when I try to do either, I get a message that says:Cannot copy X: files on this CD are read-only. You can still copy new files to this writable CD, which will replace files already on the disc. This does not make any sense to me: first, why should the supposed read-only status of files on the disc prevent me from recording new files on unrecorded sectors, and, second, why the Hell should I however be allowed to delete the files I already have in favour of new versions, but not to get in new ones? Am I missing something, has Windows gone mad, or is there something I don't know? It's driving me mad, because I have a lot of graphic files to transfer.

In each case this happened, I had used the CD before. One of them, in particular, had had additions made to it several times, as I got hold of various issues of a particular series. I had had no problems before. The message makes no sense.

All right, so we're dealing with a multisession CD then. Does this now happen with any CD so used, or only some of them?

Also, did you only start getting the error with the new computer/new windows version? (What version of Windows is this?)
