Hi Dan,
to your first point: Did you activate tab caching? Otherwise the script won't be able to fetch data from other tabs then the active one. If you need more details on this, just tell me.
Your second point: Didn't find any element where i can change "IsClickable" as well. Would be great if anyone could tell why there are that many properties that can't be changed? Though i guess it will change in 3.0
Kind regards
