INCD not formatting right

When I try to format a RW-CD using InCD v4 it carries out the format correctly but then says that the disk is Read Only. This has happened with other disks and also with an earlier version of InCD.
Also, when I insert a RW-CD the system tray icon does not change at all. In fact it looks nothing like the ones pictured in help and it doesn’t change colour.
Can anyone help?

What version of InCD? If it’s not, uninstall the version you have, reboot, and download and install the latest version. There’s a whole raft of bug fixes in recent versions of InCD.
