Hey there Peejay.
I believe that updating to the newest version of Sonar Plat, has worked out load times, and the busy write of the wave forms to track issues.....Not sure about all you say , but I have witnessed some of that sort issue , and more so more of other things, in past renderings of Sonar X3...
it could be a memory thing...but, I would try to update....to Plant latest rendition...seems to be working for some, better than previous versions...so it seems with some very good updated bug fixes.
If it does not work out...get back the money asap....if so is paid to do.
I believe all are allowed a test grace period of time ,to see into usage on the system it is claiming it works on as specified.
If that does not work out...You should be able to revert back or roll back to what works...if be so X3.x.xx...and claim a refund....of try a 20 monthly plan...just to try it out...before you go full in..or full out...
Although I am not impressed with the cash cow system of pay and update buggy codex...""That is the way it is, until it is not that way anymore""...life time updates should scare people?
To any other poster who may knows of a updated free and full working demo...try that first if so exists as a offering up to get you hooked in......wink?.
Cheers.
