TITLE   :Fastback: Mouse Click on Pause Button Doesn't Work
PRODUCT :Windows NT
PROD/VER:3.10
OPER/SYS:WINDOWS
KEYWORDS:

----------------------------------------------------------------------
The information in this article applies to:

 - Microsoft Windows NT operating system, version 3.1
 - Microsoft Windows NT Advanced Server, version 3.1

SYMPTOMS
========

When you run Fifth Generation Systems Fastback or Fastback Plus with
Windows NT, nothing happens when you click the Pause button.

CAUSE
=====

While the virtual DOS machine (VDM) is busy writing to or reading
tracks from a floppy disk, mouse interrupts are blocked. This problem
occurs because 16-bit interrupt handlers are run in the same thread as
the floppy emulation code. Since mouse events are not queued, the
button clicks and the position movement are not received during the
floppy read/write.
