Unable to automate application using desktop automation(desktop spy)

Hi,

We are facing issues to automate compass application, as this application contains applet ,we are using desktop plugin from Process studio. But while spying element it gives error.

PFA for error

I believe that you have the use an autoit scripting for that, because those applets they tend to behave like a web application, but are not webpages.
With autoit you might be able to make that window active and then interface with that.
