Thanks Erel,
I'm not trying to remove the view, I'm trying to "highlight" the view from within a service using a callsub to be able to access the UI from the service.
I sort of have it working by:
When I create a view, I store activity.numberofviews in a tag. Then from within the service I am able to use a callsub to have the "highlighter" change the background attributes of the view whose number is contained within the tag.
It seems to work, but I thought there might be a "proper" or more elegant way to acquire the view number.
