Description
While dumping a floppy disk to .img using a USB floppy drive, DIC crashes after "Closing Output file." with
"Unhandled Exception: System.NullReferenceException: Object reference not set to an instance of an object.

It did not crash dumping a CD, and I do not have another USB floppy drive handy to test with right now. The image itself appears to have saved correctly.

This issue is still present on the newest commit and with a second USB floppy drive.

This still happens on the newest commit, and this time I verified that it crashes when dumping as both IMG and DICF.

Dumping a floppy disk to .img and .dicf no longer crashes on the newest commit, tested with two separate USB floppy drives and two separate floppy disks.
