Hello,
I just installed Zotero to my pc and a blue blackground with a shadowy font appears on the left and right of the main panel, where it is written no tags (on the left) and 0 items found (on the right). I have the same version on my laptop and it's perfectly normal. It is also normal in the standalone version and when it opens in a new tab. It is that way only whe it opens as a browser pane. It is very ddifficult to read that way. Please help!!!
