I tried removing with the Remove Filter button, the dialog went away and the filter was still in the list. Restarting ImgBurn had no effect. After removing it manually in the registry, it disappeared from the list.
However, when I wrote the last post, ImgBurn appeared to be verifying the disk without issue. Now it stops @ 82% complete and hangs. And the system itself still hangs after aborting ImgBurn's verification process. A hard reboot is necessary to recover the system.
There are now no filters listed in the ImgBurn filters tool, so I'm really confused as to what's going on.
I tried removing Windows Movie Maker as I never use it and it was mentioned in a post somewhere that sometimes causes issues. But no change in behaviour.
For what it's worth, a Windows 7 Ultimate installation does not have a Sonic Shared directory in the Common Files area of either Program Files or Program Files (x86). It's something to do with Sonic's software, but I'm just lost as to what or how that might have been installed.
