I am using Kubuntu 7.04, OO 2.2 not 2.2.1, still using OO that had
came prepackaged with Fiesty. In linux the open office is word
processor and in windows its writer I think!(well I am not that sure
of writer or processor).

I could be using portableapps its free but ...... is it FOSS ? I am
strong advocate of GNU and against piracy. But any way i'll try and
check out weather Kubuntu has registry or not.

I will also try sudo apt-get clean, i think thats the best option.
