I connected the Zonbu external USB CD/DVD drive, and the blank CD icon appeared on the desktop.
I launched the CD/DVD burning application, selected the ISO source file and went to burn it when I noticed there was no “device” appearing in the target drop-down…
I’m going to reboot and try again, but this seems like a bug.
I rebooted, and the bug is still present.
Just for giggles I hit the burn button anyway, and lo and hold, it happily burned the image. So it looks like a visual bug only.
The bug hunting continues…
