I updated the pt_BR.po files and now I'm testing the translation on my Macintosh and it works really fine. Additionally, I'm also testing the translation on Windows computers. I actually tested in two different Windows based computers and the results were a little bit confusing (the first display the results correctly, the other didn't). Please, look the following results: WINDOWS XP Média var. dependente 0,004595 D.P. var. dependente 0,041708 Soma resíd. quadrados 0,227919 E.P. da regressão 0,037625 R-quadrado 0,196207 R-quadrado ajustado 0,186222 F(2, 161) 19,65016 P-valor(F) 2,31e-08 Log da verossimilhança 306,7418 Critério de Akaike -607,4836 Critério de Schwarz -598,1840 Critério Hannan-Quinn -603,7083 rô 0,365419 Estatística de Durbin-Watson 1,260998 OS/X Leopard Média var. dependente 0,004595 D.P. var. dependente 0,041708 Soma resíd. quadrados 0,227919 E.P. da regressão 0,037625 R-quadrado 0,196207 R-quadrado ajustado 0,186222 F(2, 161) 19,65016 P-valor(F) 2,31e-08 Log da verossimilhança 306,7418 Critério de Akaike −607,4836 Critério de Schwarz −598,1840 Critério Hannan-Quinn −603,7083 rô 0,365419 Durbin-Watson 1,260998 I'd realized that the problem is occurring in the line "Durbin-Watson", that appears "Estatística de Durbin-Watson" in the Windows XP. I'm a PoEdit user and tried to fix that problem editing the pt_BR.po, but I didn't found any problems in the .po file. So, what's the problem? Can you help me to discover what I'm doing wrong? Best, Henrique C. de Andrade Doutorando em Economia Aplicada Universidade Federal do Rio Grande do Sul www.ufrgs.br/ppge P.S.: Allin, I'm speaking about the pt_BR.po file that I`d sent to you. I though that it was perfectly fine, but when I made the additional tests I found this problem. I'm sorry!
