ReadLang on Google Translate page
If you set the Google Translate page to translate from your native language to your target language, enter a word or phrase, and then click on the ReadLang button, the target word or phrase works normally in ReadLang. But if you then change the input to GT, producing a new target language output, then the green line for ReadLang does not appear and Readlang does not work. If you refresh the page, ReadLang will then work with the new translated word or phrase.
The reason I like to use ReadLang in this way is to input words or expressions into the ReadLang Wordlist to practice with Flashcards. The most common use is to put "the" in front of an English noun to get the gender of the word in the target language. But it is also very useful to get and input adjective-noun combinations and short expressions.
Is there a way to keep ReadLang working on the GT page without having to refresh the page each time? Thanks.

As you’ve discovered, refreshing the page is the only way to get the Readlang clickable translations back after a page update at the moment. Fixing this would be quite complicated.
One alternative is to enter your words or phrases into the “Lookup” search box on the Words page (http://readlang.com) – this will show a translation which you can click to immediately add to your word list.
Hope that helps.
