Besides the reiteration of the
demo being available, I can affirm that your assessment about X3's release is definitely wrong, and here is why...
I pre-purchased X2, and had a bad install of X2 that made it totally unstable... since I was working 16 hour days, I kicked X2 to the curb quicker than last week's news and it took me 9 months to come back and resolve the issue. Even though stable from that point on, I did not pre-purchase X3 and waited an entire week before getting it, which was based on the user feedback here. If it had been bad, I wouldn't have X3...
I was recently replicating an experiment from another DAW (moving a single sample in Audacity) and pulled that clip into SONAR to check it. I had zoomed all the way in to see samples and was sliding the clip one sample at a time, which is why a video of your issue would help us a lot. Something as simple as zoom level /mouse used factor into the resolution of moving a clip.
