In answer to your questions below:
--Virtual memory [pagefile size] is just over 1Gb
--It does choke at the just about the same place.
--The code used to load the images into Xinteranimate is:
;;;---snip---
;nx= about 700 & ny= about 400 & nframes = 180
;---------- Initialize loop to produce images
images = Bytarr(nx,ny,nframes)
;initialize animation
Xinteranimate, set=[nx,ny,nframes], /track, title=title
;Set up 2D arrays with points that cover the whole range of data
;to set the axies ranges in Surface
zz_ = Dblarr(2,2) & xx_ = Dblarr(2,2) & xx_ = Dblarr(2,2)
zz_ = [ [zr[0], zr[1]], [zr[1], zr[0]] ]
xx_ = [ [xr[0], xr[1]], [xr[0], xr[1]] ]
yy_ = [ [yr[0], yr[0]], [yr[1], yr[1]] ]
; - - - - - - - - - - - - LOOP TO CREATE IMAGES - - - - - - - - - - - - -
FOR i=0,nframes-1 DO BEGIN

;Read image from window and add to animation
image = Tvrd(x0,y0,nx,ny,!d.window)
