Mister original poster - you have been a Sonar user for 2 years now, and have only engaged in the forum for a total of 21 posts.
This forum is a wealth of information for those who are learning, and for those who are trying to work through problems and sometimes bugs.
If you do not post your issues, along with your system specs, nobody here will know you are needing help, and you will just build frustration needlessly.
Your rather grandiose conclusion that Sonar is not worth the bother is really more of an indication that you didn't bother - you didn't bother to participate in one of the more helpful forum communities out there, and now you are crying in your milk.
When you are ready to list your issues, with relevant details, folks here in the forum will work pretty hard to assist you with your problems. In the meantime, your dumping on Sonar because you didn't invest in getting help from the forum is pretty sadly comical.
When you are ready to engage us with specifics, we will respond with assistance.
