System Workbench for STM32

Hi,

here some more information. I have this this files COscillator.cpp and COscillator.h .The .h file is included into the COscillator.cpp and the main.cpp file. In main i create a COscillator object and call some public methods.

I the main i get the following error:
Type 'COscillator' could not be resolved

But the compiler creates the .elf file which is fully working.

Anyy ideas?
I deleted the 2 files and wrote them new. Same problem. The Project was running with the previous version of System workbench without problems.

Any ideas?
