Hi David,

There was a problem with early version 2 releases where importing from
a window ID crashed the app. My workaround (until 2.5 fixed it) was
for my snapshot script to position the window I wanted to snapshot in
a set place on the screen, make sure it was at the front and then take
a snapshot of the area I wanted using global coordinates. A bit clunky
but it works.

Cheers,
Sarah
