Reduced Functionaity Java 3D OpenGl

Hello everyone,
this is my first post and can I start by saying thanks for making reprap open source, and all the support and information the community gives newbies like me.

Here's my question, I downloaded the files from sourceforge, followed the install procedure for the Host Software, ran it and it worked.
But this was on the DOS console
Error opening port : /dev/ttyUSB0
and
JAVA 3D: OpenGL 1.2 detected; will run with reduced functionality

Manipulating the view in the main screen works then stops, and there is no drop down from the view menu.
Can you help to get this functioning properly please.

This is running on a Dell Precision M50 laptop with 1GB ram, Windows 2000 SP4.

Any help with the /dev/ttyUSB0 entry would also be appreciated

Thanks

In the RepRap host software bring up the Preferences dialog window and enter the proper name for your COM port.
On my system it is COM3. You must specify the port being used for serial communication to your RepRap.
On unix systems /dev/ttyUSB0 is the default, for Windows systems COM1.
