- TITLE :Fastback: Can't Pause Backup with Mouse
- PRODUCT :Windows NT
- PROD/VER:3.10
- OPER/SYS:WINDOWS
- KEYWORDS:BUGLIST3.10
-
- ----------------------------------------------------------------------
- The information in this article applies to:
-
- - 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.
