I was finally able to download programs to the RCX using the workaround below:

1) Open the IDE and use the plugin manager to change the Lego tower port to an
   unused COM port

2) Compile your RCX program with the IDE.

3) Download and install the Bricx Command Center (BCC) package.

4) Open up BCC and you should see the dialog "Find Brick". Set the following
   values and click 'Ok'.

   COM port: <your RCX com port here>
   Brick Type: RCX
   Firmware: brickOS

3) Go to Tools->Download Firmware. Select the 'lego.srec ' and click Open. This
   should start the Download to the RCX. If everything is successful you will
   hear the 'rising chirp'.

4) Once the firmware is downloaded toggle to power button on the RCX. You
   should see 0042 on the LCD screen. The RCX should be ready for your program.

5) Press the 'grey' Prgm button. (Sometimes it chirps sometimes it doesn't).
   Go to Tools->Download Firmware. Now select the compiled version of your
   program 'something.srec'. The click Open. This should upload your program to
   the RCX. If successful you will hear the chirp.

6) Now press the 'green' run button to start your program. Press the green
   button again to stop your program.

7) To download another program I had to do the following:
    - press the Prgm button
    - wait 5 seconds
    - press the Prgm button again ( this time getting the chirp )
    - download the new program to the RCX.

Every once in a while the RCX locks up and I have to pull the batteries and
start from the beginning. It is rough but it works.
