I've just logged a support issue with Sonic because creating a "Data CD" using RecordNow Dx dies at 98% and I have to re-boot the PC to recover and unlock the drive :a
Funnily enough the CD is readable on another PC and thus the CD writing process actually completed.
DLA formats the same CD-RW ok, no problem.
