2. I have some difficulties writing in Greek with oppenoffice. Although I can write polytonic greek on linux e.g. on a "find" tag or on address bar of firefox, it was impossible for me to write polytonic greek with oppenofice. What do you suggest?
2. Oo is apparently able to spell polyphonic Greek as a google search revealed -
a hunch would be to change your location settings etc in Tools>Option>Language Setting
or have a look at this webpage - (they should be able to help you)
