Hello!

SRT> program that reads a text file and performs some calculations. I

SRT> each piece of data is read and calculations performed. If I run

SRT> window loses the focus, e.g. run another Windows program, or even
SRT> click the mouse outside the BlackBox program's window, the
SRT> program freezes and I get a BlackBox (Not Responding) message. I

SRT> Windows XP virtual machine. I thought I might have a problem
SRT> with VM Fusion, so I tried on a desktop PC running Windows XP
SRT> directly, and got the same result. Can anyone suggest a fix for this?

  The program is still running. Disregard the "(Not Responding)"
  message, it simply means that BlackBox is too busy doing your task
  to repaint its main window or handle mouse/keyboard events.
