Just for info, I've been using ImgBurn for a while now, great great program.
I just upgraded to the latest version (2.4.2.0) and I'm seeing the exact same problems as is highlighted here.
I have two DVD+-RW drives (both DVD-RAM capable) and when trying to create an ISO from a CD, the program just disappears. DVDs work OK.
DVD Drives are:
HL-DT-ST DVDRAM GSA-4163B (A106)
TSSTcorp CD/DVDW SH-S183L SB01 (SCSI)
