Can't "display" method but "print" it ?

[Markus . Grunwald]

Hello,

When I try to "display"  the result of my method  "float Class::Angle() 
const", I get the following output:

(gdb) graph display oVector.Angle()
Overloaded method instance Angle__C10CPTComplex, # of parms 1

No display apperars.

But when I try to "print" it, it works:
(gdb) print oVector.Angle()
Overloaded method instance Angle__C10CPTComplex, # of parms 1
...Badness @ 0 : 0
Overload resolution champion is 0, ambiguous? 0
$2 = 191.85878

Is there anything I can do to display this method ?

My DDD Version is 3.3.1 (i386-suse-linux). 

Mit freundlichen Grüßen
