# Cite pop-up in Texstudio doesn't show up anymore

I'm using TeXstudio 2.5.2 together with Jabref 2.9.2 and BibLaTeX. Everything in my document works fine except that when I enter \cite no pop-up with all the bibliography entries shows up. The weird part is that it didn't work at first, then after a hint of a colleague it did and now it doesn't work anymore. Now I know, that this isn't the biggest problem in the world (especially when you're using Jabref, since there's a button to push a citation to your TeX file) but sometimes it would be nice to have the popup.

Below I have a minimal "working" example (obviously if one adapts the directories) - what I'm doing is, is calling the \printbibbliography command in an external .tex file called Verzeichnisse (which is then called by the the input command) - this is due to said tip of my colleague which acutally worked at first.

Does anymone have an idea to make this thing work (again)?

\documentclass[a4paper, parskip, 11pt, chapterprefix, numbers=noenddot]{scrbook}

\usepackage[ngerman]{babel}
\usepackage[T1]{fontenc}
\usepackage[backend=biber,style=alphabetic,sorting=anyt,maxalphanames=1,maxnames=99,
maxcitenames=2,natbib=true]{biblatex}

\renewcommand*{\labelalphaothers}{}

\input{Kapitel/Verzeichnisse}

\begin{document}
\end{document}

From my work with TeXstudio I assume the file with the bibliography entries must be opened in TeXstudio. –  Qrrbrbirlbel Apr 2 at 21:55
Thanks for your answer - that's what I acuatlly did at first and it didn't work. That's also why I tried this detour via the external .tex-file, which actually worked at first. I just tried to open the bibliography file in the main file, but the popup still doesn't show up –  Bobby Apr 3 at 8:29
