I'll keep on eye on things.
To the Original Poster (musicaz) - Welcome to the Sonar forums - sorry you are having or have had a frustrating time getting the Addictive Drums to work, and that is extended to any other issues you have with your X3 experience.
If there is functionality or work flow with X3 that you don't care for, I don't know if anything can be done for that, but I CAN tell you that X3 has been extremely stable for quite some time, if you get it up to its current maintenance level of X3e.
I would also assure you that if you were to engage with the folks here in this forum, and list out the details of your issues - each in a separate thread, with as much detail as you can provide, there are quite a few folks here - myself included - that would work with you to try to resolve those issues.
I would also suggest that since there are not a bunch of threads here with X3e crashes or show stopper issues, that some number of your issues might well be able to be resolved - or at least given one or more workarounds. In other words, your issues may well be local to your PC, and therefore fairly likely to be fixable.
It's completely up to you - If you wish to address your issues - participate in fixing them, or not. I would suggest you would be missing out on what is considered by many to be one of the best and most stable releases of Sonar ever put out, if you decide to just sit back and take pot shots at it.
I stand ready to assist, and I believe others do to.
