Hi Daniel @d-biehl.
Just reporting possible issue with pre-release version of robotcode:

I have tried pre-release version by installing: robotcode-1.3.0-dev.4.vsix
Running tests works for me nicely, however if the test is stopped on brakepoint, I cannot use Interactive debug console.

@JanDubcak I work on this, but it take a few days ;-)

@d-biehl Thanks a lot :)
