Thanks, @oweng, @ROSt53. I may clarify, the indent will vary if using different fonts in one paragraph but shall not vary because of changes in font size. I guess it was due to a dirty patch made by some hired Chinese contributors. (OpenOffice.org failed to gain no popularity in Simplified Chinese market, and no Chinese native developer involved except for a Chinese company who actually forked OOo into their own Proprietary Product, RedOffice.)
