No, I'm not closing any screens. Or at least not explicitly. I pasted the entire file below for a better reference.
The process attempts to locate a code in the registry. If a code is not found then the roKeyboardScreen is displayed to collect the access code. After the user enters the code the script then takes that code and attempts to query the url for verification.
After your post, that got me to thinking. I don't have a background screen open. So maybe after the roKeyboardScreen returns the entered characters, is that screen then being closed?
