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


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.
