In my table of contents, some of the dot fills do not end at the same place as the other lines. What is causing this and how can I make the dot fills uniform? A red oval highlights the problem in the following screenshot:

Extra dot in ToC

Edit: It looks as if the page number "101" is slightly less wide than the other page numbers, allowing just enough room for an extra dot. This is probably the cause, but I still don't know how to fix the problem.

Edit 2: Minimal working example below. The document class is located at https://github.com/wannesm/adsphd/blob/master/adsphd.cls, and is quite long -- apologies for the inconvenience.

Please help us to help you and add a minimal working example (MWE) that illustrates your problem. It will be much easier for us to reproduce your situation and find out what the issue is when we see compilable code, starting with \documentclass{...} and ending with \end{document}. – Christian Hupfer Apr 22 '14 at 9:19
In my point of view, there is a large gap at the end of preliminaries and the beginning of the dotted line. On a second look on your image, this is true however for 5.3.1 and 5.5 also :-( – Christian Hupfer Apr 22 '14 at 9:27
Your edit does not improve the situation for possible helpers. As @ChristianHupfer suggested, add the code that yelds this output (or some minimal working example showcasing the undesired behaviour). As far as I know, there aren't any fortunetellers on TeX.SX... – Ruben Apr 22 '14 at 9:27
Indeed. I suggest you make a copy of your document where you remove all text but keep the headers (but not past this chapter). Do you still get this anomaly in the table of contents? Then remove stuff from your preamble that you need only for that text that is removed anyway. Check if there is still a problem. If there is, you have something to post that will help us help you. – pst Apr 22 '14 at 9:33
I am lost sure I saw a similar (identical) question here... – Dror Apr 22 '14 at 9:44

This is a problem with microtype. Use


for the Table of Contents.

Yes, you are right. If one removes \usepackage{microtype} from that class file, the error vanishes also! Perhaps, one should notify the maintainer/creator of the class file about this 'feature'? – Christian Hupfer Apr 22 '14 at 10:03
Great, thanks a lot! Is this a bug in microtype that will be fixed soon? – Starlyght Apr 22 '14 at 10:08
It is mentioned in the microtype documentation in the "Hints and caveats" chapter as one of the places where you might want to disable protrusion. I'm not sure it can be seen as a bug in microtype as such. Rather I think that classes that use it ought to redefine \tableofcontents like this. – pst Apr 22 '14 at 10:13
@ChristianHupfer I've notified the maintainer of the class, should be fixed soon - thanks! – Starlyght Apr 22 '14 at 14:31
