Still present in beta 10.  The behavior of this bug appears to depend on 
the position of the Pov window and can be reliably repeated on all Win2K 
systems I checked.

Confirmed in <Xns### [at] 204213191226>

Code used:

box {<-4,0,-4> <4,4,4> pigment {rgb 0.5} hollow}
box {<3.75,1,-3> <4,3,3> pigment {rgb 1} finish {ambient 10}}
sphere {y,1 pigment {rgb 0.5}}
light_source {y*3.99 rgb 1}
camera {location <0,2,-3.5> look_at <0,2,0>}

global_settings {

  max_trace_level 1

  radiosity {
    recursion_limit 10

    pretrace_start 0.08 pretrace_end 0.04 count 35 nearest_count 5
    error_bound 1.8 low_error_factor .5 gray_threshold 0.0

Confirmed in <Xns### [at] 204213191226>  The problem is not a 
text selection but rather that the error highlight bar is not always 
cleared even after a successful render.

Confirmed in the original thread and in
<Xns### [at] 204213191226>.

Ken Tyler was the only person who asserted that the behavior described 
should not be fixed.  His rationale was that this bug shouldn't be fixed in 
3.5 because it existed in 3.1g.  

Bob H ultimately agreed with Kevin Ellis that "the box container object 
itself does seem to cast a shadow when it should not be."
