This is on a symbolics running genera 8.1.1 and CLIM 1.1 but the problem also appears on the SUN

I need to allow only certain instances of a class to be accepted in a certain accept statement.  
I supply parameters which are used in the determination. Present-typep correctly evaluates the
parameters and returns nil for the instances that are not supposed to present.  Unfortunetly the 
instances present--ie a box is draw around them--anyway.  I even hardwired presentation-typep so
it always returned nil and that made no difference.  If i use the help key to get the suggestions for
what instances are acceptable i get the correct list with only the intances that pass the test in present,
which is based on the parameters in the accept statement.

I tried using the modifications to identity-translator-applicable-p that were posted here recently
but that didn't seem to help.  

The basic question is how do I limit which instances of a class are mouse sensitive?


the basic code layout is 

        (accept `((unit  :parameter  ,test-value ...))

	presentation-typep
              (if (function test-value)
                   t
                   nil)


Thanks for any help.
