Notes


Notes

Windows NT

(1)	When using the eject button on the CD-ROM drive itself to eject and change a disc, the display of track number and playing time will not be correct, even if the Drive Select box is used to select the drive. (The information displayed will still be for the old disc.) To update the information, reset the view once after the disc has been ejected (drive slot empty) and then once more after inserting the new disc.

There is no complete solution for this problem which is related to the way Windows NT handles the 16-bit environment.

If the eject button of MJAudio is used to change a disc, the display will be updated correctly.

Windows 95

(1)	The number of tracks for multi-session discs is not displayed correctly. This is a limitation imposed by Windows 95, and there is no workaround.

Multi Instance command
Multi Instance command (File menu)

When this function is ON, a check mark appears to the left of the menu item. In this condition, a new window will be opened every time MJAudio is started, allowing several instances of the program to be running at the same time. This allows playing discs in two drives simultaneously, but since problems can occur in such a case, the function should normally be set to OFF.

If the function is set to OFF after multiple instances of MJAudio have been activated, the instances already running will not be closed, but new instances cannot be started.

Precaution

Exercise care when using this function, because multiple instances of MJAudio attempting to control a CD-ROM drive at the same time may lead to problems. Also, it is not possible to play two discs in a CD-ROM changer at the same time. If this is attempted, irregular disc changes may occur.
