IAR switched all files to not compiled after linker is done

Hi,

I'm using IAR for arm v7.40.

After adding a few new files to my project (not sure if this is the cause) i have the following effect.

When I click "Make", all the files compile and the red '*' goes away to indicate that it compiled.

As soon as the linker is done successfully all the files immediately get a red '*' back.

This is frustrating because I need to wait a few minutes each time I want to enter debug for example.

Does anyone know of any possible causes for this?
