Text spellchecker update problem

[ScrKiddle]

I have a large TXT file, some words are incorrect.
The spellchecker does underline the wrong words.
I use the Find-Replace functionality to find wrong words ans replace them all at one with correct words.
Wrong words are at the beginn of a new line that is warped at column X.
The corrected word is shorter after replace-all and fits in the line before the line-warp
Now the spellchecker does not update the red underline, corrected words appear still with a red underline, in one line with line-warp the wrong word was after the line-warp after correction it is before the line-warp but the red underline from the spellcheckers keeps sticky after the line-warp, it does not respect the new situation and even keeps the beginning of the line after the word-warp read as long the incorrect word has been before it got corrected and switched before the line-warp, the spellchecker even keeps the new situation with spaces between the words red marked.

Example

This is a long line with
somewrongs in it

Search-replace all "somewongs" with "faults".

This is a long line with faults
in it_____

(it even marks the new situation red after a real hard line-break.)
