In fact there were further issues. I see that additionally the rtFil handler is already fixed, now there is still is a non functional callback to auto refresh the list. Callback functions have to be global unfortunately because they use another scope, so "REO_roll != undefined" will always be false, and you cannot call the required functions on it. But just add a "global REO_roll" (yes, we all hate globals...) before defining the rollout and the auto refresh will work.
Then: please update the version variable to 0.4, not to 4.0 :) And the button state (pressed) when the script is displayed (on isChecked()) is gone as well as the docking option. And I'm no friend of fixed layouts.
But those are features I want to have for myself primarily and do not affect functionality. With the exception of removing the fixed layout where I struggle when it comes to .net controls, I have brought back those features into your previous version here for personal use :)
Good Luck
