One way to locate the problem is to build ddd with profiling enabled.
For that, assuming you are using gcc, build ddd the usual way:
./configure --prefix=xxx, edit "ddd/Makefile" and add "-pg", then
make and make install).
Then launch ddd and reproduce the sequence that shows the problem.
Then "gprof /path/to/ddd" should show the hot spot.

If possible, provide a patch against the CVS repository.
