# TeXstudio Is Not Responding

I have been using TeXstudio for some time now, and have highly enjoyed using. However, just now it has been acting up. Whenever I open the program, my cursor always reverts to the wait-cursor, this one , and it is rather annoying. Not only is this an issue, but I TeXstudio won't compile any of my documents.

Has anyone ever dealt with this issue?

EDIT: Here is the code that is apparently giving me trouble:

% Regular polygons
\documentclass{article}
\usepackage{tikz}
\begin{document}

\newdimen\R
\R=0.8cm

\begin{tikzpicture}

% Indicate the boundary of the regular polygons
\begin{scope}[yshift=-3\R]

\draw (0:\R) \foreach \x in {60,120,...,359} {
-- (\x:\R)
}-- cycle (90:\R) node[above] {Hexagon} ;

% 360/7 = 51.4286 For PGF v < 1.18 we have to round to the nearest
% integer. Newer version support fractional angle values.
% For a more accurate result use the sequence
% {51, 103, 154, 206, 257, 309}
%
\end{scope}

\end{tikzpicture}

\begin{tikzpicture}

% Indicate the boundary of the regular polygons
\begin{scope}[yshift=-3\R]
\draw (-0.8,0) -- (0.8,0);
\draw (0,-0.7) -- (0,0.7);
\draw (0,-0.7) --
\draw (0:\R) \foreach \x in {60,120,...,359} {
-- (\x:\R)
}-- cycle (90:\R) node[above] {Hexagon} ;

% 360/7 = 51.4286 For PGF v < 1.18 we have to round to the nearest
% integer. Newer version support fractional angle values.
% For a more accurate result use the sequence
% {51, 103, 154, 206, 257, 309}
%
\end{scope}

\end{tikzpicture}

\end{document}

• This may sound stupid, but did you try turning it off and on again? The complete pc. – Johannes_B Dec 12 '13 at 15:59
• Uninstall, clean registry and reinstall could be a start. Could you tell us when and how it started or what you did before you noticed the issue? – azetina Dec 12 '13 at 15:59
• @azetina I believe it began when I was practicing making drawing with the tikz package, and I actually used an example from the tikz website. For some reason, TeXstudio automatically saved the file as texstudio_s13480.tex Did I perhaps overwrite some important file? – Mack Dec 12 '13 at 16:12
• So, if the restart does solve your problem (temporarily, which i think it would) and you try to compile again, does it again go into nonrespondence? Maybe your document, that you try to compile is missing a ; which causes LaTeX/TikZ to search for that (sometimes quite longish)... And i don't think, you deleted an important file. – Ronny Dec 12 '13 at 16:24
• Restarting the computer did not work. – Mack Dec 12 '13 at 16:42

\documentclass{article}
\usepackage{tikz}
\begin{document}

\newdimen\R
\R=0.8cm
\begin{tikzpicture}
\begin{scope}[yshift=-3\R]
\draw (-0.8,0) -- (0.8,0);
\draw (0,-0.7) -- (0,0.7);
%        \draw (0,-0.7) -- % here is the problem
\draw (0:\R) \foreach \x in {60,120,...,359} {
-- (\x:\R)
}-- cycle (90:\R) node[above] {Hexagon} ;
\end{scope}
\end{tikzpicture}
\end{document}


Basically, the erronous lines wants to draw a line from corrdinate (0,-0.7) to (--) well, and then there is nothing, but a new \draw command. So the path was never finished, causing trouble.
