I appear to be unable to spellcheck (auto-spell or manual check) documents created by a right-click from the user’s desktop or from a folder, in Windows (Vista/7) 64-bit - and I get the same problem with both LibreOffice and with OpenOffice. Spellcheck still works correctly when launching Writer first, then creating a new document.
Move mouse pointer to blank space in a folder or move mouse pointer to blank space on the user’s desktop.
Right click mouse.
Select New, then select OpenDocument Text.
Hit return or enter a file name for this document, then hit return.
Double click the new document you have created to open your document in (OpenOffice or) LibreOffice Writer.
In Writer, type random text (ie text that would produce spelling error, ‘ghgy’ will do).
Text not highlighted with red wavy line as being misspelt.
Check document spelling manually and no spelling errors are detected.
Close your document and LibreOffice, then try this:
Launch LibreOffice and start new Text Document. Here, type in misspelt word, followed by pressing Return, and the error is automatically discovered by LibreOffice. Why does spellcheck work in one instance but not the other?
