I have been using the Greek font BwGrkl (You can get it free at:
http://www.bibleworks.com/fonts.html ).  This font uses the characters: `,./ and
v for overstrike accents and breathing marks.  In other words these add a mark
over a previous character rather than inserting a new character.

I was running OO 1.0.3 on my MAC (under YellowDog) and this font worked
beautifully.  I just recently switched to using my laptop (Running Win98 and OO
1.1) because I am on the road.

OO 1.1 displays the greek characters fine, but when I try and enter an
overstrike character, I get the English equivalent character on the screen and
not a breathing or accent mark.  I checked MS Word on the same machine and it
displays the overstrikes correctly.

For instance if I type: avgaph,
I should get the Greek characters agaph with a smooth breathing mark over the
'a' and an acute accent over the 'h'

Thanks for your help.
