I start using TexnicCenter (2.02 stable) as an editor to write LateX files. During the installation I make sure to install different languages dictionaries especially the french one. When using TeXnicCenter, I have tried several time to switch the spelling (see picture). But it seems like even after changing the spelling options and re-starting the software, the speller checker when writing the text remain set to English dictionary. Do someone actually successfully change the spelling on TeXnicCenter?
Seems like, this is not an issue anymore. The right way to change the speller checker is to go to Project -> Properties and change the project language.
