That's a different topic, Al! The issue here is screen resolution and
monitor settings. Visio generates an image for the entire page even if you
are only zoomed in to display a portion of it. That image is a maximum of
32,000 (roughly) pixels wide. When you divide by the current number of
pixels in your screen resolution and then by the DPI setting of your
monitor, you get a maximum zoom level that Visio can display.
This limitation goes back to Windows 9x operating systems and is no longer
necessary. I believe that Service Pack 2 of Visio 2003 removed this
limitation. Otherwise Visio 2007 will.
