I am rephrasing my problem :*)
This is what I do:
Type a phrase in Search/Index box
A list of items appear on the left-hand panel
Click on one item
The item on the list is NOT grayed.
(The topic appears alright on the right-hand panel and the
keyword highlight appears fine)
I am having another problem - with hotspots!
In one, the topic appears "blank" in the edit-mode, but
preview shows all the text with the hotspots (there are multiple).
