cgSnaphot doesn't detect currently open windows [message #76910]

Hi there,
I'm having a similar problem to what was reported here:
https://groups.google.com/d/topic/comp.lang.idl-pvwave/6NZ7D ekqqCI/discussion

when I call cgSnapShot I get a message "no currently open windows. Returning"

However, I am following David's suggestion. My code reads like:

cgIMAGE, array, /order, /KEEP_ASPECT, /WINDOW
wid = cgQuery(/Current)
snapshot=cgSNAPSHOT(filename=Output_file_PNG, /PNG, /NODIALOG, WID=wid)

Am I still doing anything wrong?

thanks

JP
