Wa rni ng: If you zoom in too far, you can exceed the
limit of virtual memory, and crash 3ds Max. When you
perform a zoom that requires more than 16 megabytes
of virtual memory, an alert asks if you want to display the
background during the zoom. Choose No to perform
the zoom and turn off the background. Choose Yes to
zoom with the background image. Your machine might
run out of memor y as a result.
