ddd-3.3.9

Dear Folks:
I just downloaded and installed ddd-3.3.9 on my Slackware Linux 9.1 
system (2.4.22 kernel,  gcc 3.2.3).

I had been used to using ddd-3.1.5 that came with an older Linux 
distribution. I notice several things do not work in my installation, 
for exampe:

1) I cannot find any way to delete a display. If I right click on a 
display and move
down to "Undisplay", nothing happens.

2) If I attempt to "drag" a display, I get the little 4 arrow icon and 
it will move with the mouse,
but the display remains where it was. This is a pain in the ass.

3) It doesn't appear to dereference pointers that are members of an object.
The "Display *()" is "grayed out".

4) The "Show All" and "Set Value" options that were available in 3.1.5 
when right clicking
on a data display are similarily "grayed out" and not available.

Is this the normal condition of the newer ddd, or do I have some problem?
