Hi. I use the translate tool a lot, and the same problems keep happening in my case (english wiki to portuguese wiki).
- I translate an article, insert categories of portuguese wiki, save and leave. When I come back latter, and publish the article, the categories I inserted come like this "Category:Primeiros-ministros do Egipto". This is wrong. The word "category", in english, should never be there, and it keeps happening.
- I start translating an article, and it soon reaches a point where I get a message that someone (me) is already translating it, and from that moment on, I cant continue translating it. It still shows in my list of translations in progress, but I cant continue it neither delete it... it's just sitting there... without letting me doing anything.
- I often start translating the Introduction of the article, ignoring the Infobox above. Every change I do to the text, the page scrolls up by its own, forcing me to scroll down again. I then continue to do something, and it keeps scrolling up...
