[R-SIG-Mac] Problems with R.app GUI

I am experiencing the same problem/flaw in the GUI for R 2.3.0 that a few other people have posted concern about. 

With R-GUI-3121-2.3
Entering demo() at the prompt results in the following message:
2006-05-10 12:31:26.370 open[1512] LSOpenFromURLSpec() returned -10814 for application (null) urls file://localhost/tmp/Rtmp04NeEd/RpackageIQR10d63af1.
Entering library() at the prompt results in the production of a TextEdit file titled "RlibraryIQR60b7acd9"
and available libraries are listed in this file.

With R-GUI-3114-2.3
When I try demo() or library() a window should be produced that contains a list of demos and libraries respectively (if they are available with the libraries currently loaded). The windows are not generated and there is no feedback from the prompt or GUI.
Additionally when one uses the the package manager, package installer, and data manager from the GUI, they work correctly until one closes them. Even though they are closed they continue to be available in the Window menu.

I had the errors above using R.app in both an Admin account and in a user account without admin privileges.
My system is a Powerbook G4 1.67 GHz with 1 GB of ram running Mac OS X 10.4.6
I had no difficulties with R-2.2.1.

As an aside - 
For those having similar problems, I recommend using R in the terminal with library(tcltk). One note though, apparently something has changed in the implementation of X11R6 on MacOSX 10.4. I used to have my display variable set in my bash .profile as:

export DISPLAY=0:0

Apparently the correct setting is now:

export DISPLAY=:0.0

I haven't yet explored the reason for this, I just know that it works.

I hope I have provided enough information to assist in identifying my problem and the continued debugging effort with the GUI.

Thanks for any and all assistance.
