I mistakenly posted this on the AdBlock forum at: http://aasted.org/adblock/viewtopic.php?t=2197When displaying the list of filterable elements those that have been blocked are shown in a red font.
If I click on one of these to see or modify the filter that suppressed it the highlight bar in the main list makes it impossible to see the the underlying URL itself.
Workaround - just discovered
Clicking on the Cancel button but moving the mouse without releasing it leaves both the list view line and the matching filter visible
IIRC this was/is also a problem with the last version of AdBlock I had used too.
