window.pick function over sub-window

[omidbrb]

Hi,

I have a function that examines all the pixels of the MainWindow using the window.pick function. The problem is that when I use a sub-window instead of MainWindow, I get strange results. Specially, the window.pick command returns "no object" over the portion of the MainWindow that hasn't been occupied by the sub-window. My question is, does the window.pick function works with sub-windows?

Best,
Omid
