There seems to be some trouble. I tried this program on SGI, IDL version 5.0
and after changing 'win' to 'X', I get an error on the contour call (here line
19) after set_plot 'z'.

---program--(spaces removed) -------------------
pro procont
nx=10
ny=10
zzm=dblarr(nx,ny)
xx=indgen(nx) & yy=indgen(ny)
zzm(*,*)=0.d0
zzm(5,5)= 1.d0
set_plot,'X'
contour,zzm,xx,yy,/fill,levels=2
set_plot,'z'
help,zzm,xx,yy
contour,zzm,xx,yy,/fill,levels=2
device, /close
end
---Result -----------------------------
%Compiled module: PROCONT.
IDL> procont
ZZM DOUBLE = Array[10, 10]
XX INT = Array[10]
YY INT = Array[10]
% Array dimensions must be greater than 0.
% Execution halted at: PROCONT 19 rbianc.pro
% $MAIN$

Maybe this will help track down the problem?
