Hi Armando,
It could be that Notepad++ is using Tabs & hiding the fact from you.
You can check whether you are using spaces or tabs here ...
Within Notepad++, go to Settings, then preferences, then "Language Menu / Tab Settings".
In the "Tab Settings" box, is "Tab size :" set to 4 and the "Replace by space" checkbox checked ?
(This is probably the
something that automatically converts tabs to spaces or vice-versa
that Marilyn was asking about in your duplicate
thread.)
Hope this helps
