Image for DOS does not consistently update progress or times (times may stop while waiting for CD/DVD drive, etc.).
Image for DOS is unable to update the elapsed time while the program is waiting for a device to respond.
Try enabling the BGProgress option. This option can be found in the [Options] section of the IFD.INI file or it can be specified by using the /bgp option on the command line. To enable the option, add BGProgress=1 to the IFD.INI file or add the /bgp option to the command line.
Additional information on this option:
Use this option to enable updating the progress and elapsed time in the background. When you enable background updating, Image for DOS can update the elapsed time even if the program is waiting for a device to respond.
Default if omitted: Image for DOS updates the progress and elapsed time directly, rather than in the background. (This is the default behavior because some systems lock up when background updating is enabled.)
