Notepad++ "Replace by space" failure

Question

As I understand it in Notepad++ 6.5.3, checking Replace by space under Settings > Preferences > Tab Settings > [Default] causes the specified number of spaces to be entered into the document when the tab key is pressed. It doesn't. Instead, a tab character is inserted as revealed by Show All Characters. Is this an ID10T error?

Answer 1

I don't know why, but uninstalling and reinstalling fixed this.

Answer 2

This setting is different for each language. In the Tab Settings menu, highlight the language that you're using and either change the option there, or make sure that "Use default value" is ticked so it uses the option you set under [default].
