Slideshow: Delete a disk image stuck in VirtualBox

Virtual Media Manager dialog box

Clicking the "Check" button takes you to the Virtual Media Manager dialog box, and under the CD/DVD Images tab, you discover that, despite your efforts to remove the recently deleted ISO from the list, the "Remove" button is greyed out and unable to be used. In other words, you can't exactly resolve this issue right off the bat.
