Every once and a while I lose a network drive for a split second but it recovers without reconnecting the share/etc. However, imgburn cannot recover from this even though I can bring up a DOS box and access the drive.
I would like to see that the source file (during a burn) seek position is stored. If a network issue loses the drive, it should be possible to attempt to re-open the file (fclose() the original handle) and continue from the previous seek position. Otherwise, when this happens I coaster a DVD.
