Snapsie - Failed to get HWND for browser (is this a frame?)

[wipe]

I get this error when I execute the saveSnapshot() method.
Everything works fine when the app is deployed on my local machine,
but when I deploy it in a server, get this error, i would appreciate
if someone could help me with this.
Thanks in advance.

Did you build from master? Or are you using the old DLL floating around?
