Fastback: Can't Pause Backup with Mouse

ID: q103743

• Microsoft Windows NT operating system version 3.1
• Microsoft Windows NT Advanced Server version 3.1

SYMPTOMS

During a backup, Fastback displays a Pause button. You cannot choose this button with your mouse. However, the SPACEBAR and ENTER keys both activate the Pause button, pausing the backup.

CAUSE

Fastback programs the floppy disk drive controller directly. Using direct memory addressing (DMA), it writes data to the floppy disk. During this time, no interrupts can occur. Because keystrokes are cached and returned on timer clicks, keyboard commands are interpreted. However, mouse moves are not cached; they are lost during DMA writes.

RESOLUTION

There is no workaround at this time.

STATUS

Microsoft has confirmed this to be a problem in Windows NT version 3.1. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
