Not to be too rose-colored glasses here, but the more you dig into any piece of software the more likely you'll find quirks. Or in some cases, pilot error...at the risk of public embarrassment, one thing that really screwed me up when cutting and pasting pieces of audio with the intention of creating repeating audio was that the lengths never seemed to be quite right. Then when fooling around in preferences I saw that snap defaults to snapping to audio zero crossings. Once I unchecked that, the lengths were spot on.
 
As to the slippage issue, I too have not been able to reproduce regardless of the metronome setting but I couldn't tell you why I don't experience it any more than I could tell you why you do!

Yeah, I'm not expecting perfection, I just don't want to keep getting bogged down with technical issues when it's hard enough dealing with musical composition! But ever since I upgraded to X1 it feels like whatever I do, I find something new and annoying that slows me down. And I've been using Sonar for over a decade now! I guess everyone has different ways of working and a lot of the things that irritate me may not even be noticeable to others.
 
And I remember doing the same thing as you years ago with regards cutting at snapped audio zero crossings!

Yes it's been reported against X3 by a few people already, but it makes me crazy seeing all these complaints about it because I have never been able to reproduce it in any meaningful way.

How many copies of Sonar are sold compared to the number of members here ?  How are those others going to figure this kludge out, by divine revelation ?
 
At least one aspect of the bug isn't hard to reproduce.  Just throw together a few midi notes in the PRV and then define a short loop somewhere over them.  With the metronome off, every few iterations a note will drop out until there's nothing left.
 
That's the problem with at least X2.  A newbie like me gets all excited and tries out a new trick and immediately hits a bug, wastes hours wondering what the heck is going on, come on here and finds out the bug has been around for years.
 
I'm beginning to sound like Beepster maybe it's because I see his point.

Sorry Paul, but this simply isn't true. For me, and I believe for the vast majority of users, this issue is not reproducible.

I guess I must have received a special copy of X2  :-)

I think it's pretty clear that it's the environments that differ, not the application.
