I should say that the problem persists even if I compute device coordinates *after* creating the resizeable graphics window. The revised code is below.

But the problem is fixed if I take David's recent suggestion and add a

WSet, cgQuery(/Current)

after the cgplot command.

pro test,window=window
x = indgen(10)
y = indgen(10)

cgplot,indgen(10),indgen(10),window=window,psym=2

; Let's do everything in device coordinates
data_low = convert_coord(x,y-0.5,/TO_DEVICE)
data_hi = convert_coord(x,y+0.5,/TO_DEVICE)
xd = data_low[0,*]
yl = data_low[1,*]
yh = data_hi[1,*]

if keyword_Set(window) then cgcontrol,execute=0

for i=0,9 do $
cgplots,[xd[i],xd[i]],[yl[i],yh[i] ],/device, addcmd = window

if keyword_set(window) then cgcontrol,execute=1
return
end
