@donho Sorry for my late response, but I forgot to answer over the weekend. :D
I’ve tested your fix and the bug is now semi-fixed:
After replacing the Notepad++.exe I’ve started Notepad++ and the bug was still present for Java script files. Then I went into to settings dialog and modified the value for the Java script tab width. After modifying this value everything was fine. This behaviour changed in comparison to the unpatched Notepad++.exe where the tab width keeps wrong after modification in the dialog, so your fix worked at this place.
Unfortunately your fix is not used in a recently started Notepad++. You must go into that dialog and change the setting first, otherwise your fix doesn’t work.

So there should be one place more to fix.

Kind Regards

I use the Vibrant Ink “theme” when editing TCL scripts.
Using the Style Configurator, when I change Language: TCL STRING to pink, all the ‘{}’, ‘[]’ and conditional operators turn pink… judging by the list of Style: types offered for TCL configuration, there is something really hosed up 8( since the list is the same for C, C++, Java, C# RC and TCL.

I see also after the update to 6.8.1 a complete freezing of my Windows 7 system

It could be the Source Code Pro font issue.
Please use 6.8.3 in which this issue is solved.

@Moltres-Rider You can always use Plugins Manager to get it back.
