We are “playing” with Wildfire & Spark and I have installed the “Translator Plug-in 1.0” inside Spark (2.0.6). When I open a chat session to someone I see the translation drop-down list and select English-French (for example), I type my message and hit send. On my colleagues Spark he gets the message in English.
I have tried a variety of options, such as type message first, then select the translation, Highlight the text etc etc.
for me Spark v2.0.8 with Translator Plugin v1.2 works fine, using a direct internet connection and also using a HTTP proxy server without authentication.
while it displays “???” (“English to Japanese”) and “??? ???” (“English to Korean”) as squares, so it seems it has a problem with the used font. (Using Firefox I can see more meaningful text symbols).
“Englisch zum Deutschen”, “Inglés-español”, “Anglais-français”, “Inglese ad italiano” and “Inglês ao português” are translated and displayed fine.
I can confirm that 2.5beta2 and Translator 1.2 work for me. Although I had to uninstall the translator 1.0 before it would tell me that there was a newer 1.2 version.
