Hi Erich,
thanks for your answer.
I am only working on a "local" machine with Windows 7
on a normal(mechanical) Harddisk, no SSD
and did not install anything in addition, only the MCUXpresso from the NXP Website.
So, i think, the spell checking ist directly from this installed tool.
It is now not a problem, because i dont want the spell check in a programming language,
but it need lot of time to find the reason.
but wondering that you dont have this problem.
I will test it also at evening on my home PC.
