I believe that these circles result from the activity initiating a new 
top-level window. Sugar provides an activity with a window. It is 
expected that the activity will pack it's widgets into a vbox in that 
window. Imported activities naturally create a top-level window.

os767 and Firefox-6 activity
start firefox
click on a file link to download
exit firefox after
left a gray circle

(Actually, it almost always leaves behind one
or more circles but I have not done exhaustive
testing to determine how many or under what
conditions.  It would be easier to start from
an understanding of how the circle gets there
to begin with (what is being used to trigger
the circle's appearance)...
