[Tex/LaTex] TexMaker is not detecting spelling errors for texts copied from another source

texmaker

I am using TexMaker on my Mac. I have been using it for years. But I always realize that when I copy texts from another source (e.g. Word documents), it doesn't check the spelling errors for these specific texts.

Any idea why this is happening, and how to fix this problem.
FYI: I have a spelling dictionary (en.GB) file already in my Preference.

Thanks in advance!

Not sure if you have found the answer, but I had a similar problem.

I went to Tools > Options > Language Tab > and then checked Use background spell-checking and my spell check came to life within the document.
