Another followup.  First, I should thank you for that piece of info.  I was indeed not aware of that particular property.
 
I tried: pointer-events:painted
... and at the suggestion of a friend, I tried: pointer-events:none
 
 
Results:
 
 
Opera -- works
 
Opera (no pointer-event style):
 * click through works fine (canvas non-blocking) -- links, and various mouse events work on the document HTML body
Opera (pointer-events:painted):
 * same as above
 
 
Firefox Gecko/20100804 Minefield/4.0b3pre -- very buggy
 
(no pointer-event):
* blocks everything underneath the invisible canvas
(pointer-events:painted):
* blocks everything underneath
(poiner-events:none):
* this seems to work
 
 
 
uzbl git.20100403-2
* click through works (canvas non-blocking)
 
 
 
----------------
So, would the conclusing (based on the specs and the results) be that Firefox is the problem here and I need to file some bug report(s)?  ... or is there any vagueness in the spec that might be the cause?
