I have configured this Target in the Manager:
https://docs.google.com/a/airweb.de/file/d/0B-SqT7Z2QCxaZ0dMY0hmcndqMndnWDE2TmZsQ3NBTTVFV09r/edit
It's marked with 5 stars, so recognition should be excellent. However it seems to have real trouble recognizing it, especially on this image:

When I try to get it recognized by only having the Target in view of the camera, and nothing else, it works pretty well but still has issues sometimes.
For additional info - I have configured 2 more targets and they get recognized without any issues on the same image the first target is problematic on. Here they are:

I hope you can help me shed some light on this.
