Z-buffer and /noerase problem [message #41693]

Ave, IDL users!

I've got two contour maps that should be drawn over an image, and I'm using
contour with /noerase key.

One could expect that the second contour would be drawn over the first one.
Strangely, if I use "set_plot, 'z'" command, the order is reversed (the
first one is over the second one).
I cannot reproduce this feature in a simple program to post here, because my
code is huge, so my
first thought was:
"OK, another bug of mine" but, if i change my code just by using "set_plot ,
'win'", then I got the right order. So: has anybody ever heard something
like this?

Thank you very much
