Help - Uploading to Arduino crashes laptop with XP

I just got my Freeduino today and I am using it with the nuelectronics ethernet shield.

I uploaded some simple examples to the unit - and all worked perfectly.

I am now trying to upload about 6K example of Webserver by nuelectronics and it crashes my laptop each time during the upload process. No response to mouse or CTRL-ALT-DEL

I'm powering the board from the USB and using Arduino 0012

Any help appreciated - but I'm in the meantime I'm going to try another PC
