Which version are you using? I checked all examples before the release of Laz 1.8.0 on Windows, and I think Juha did the same on Linux.
Checking a hundred sample projects really is no fun. So, if you find something which is not working in the current release or in trunk please file a specific bug report, and it will be fixed. It will not be fixed, however, if users are lamenting about poor documentation and non-working examples in a general way.
