When X3 was first released, I managed to get a small project into a very weird state.  I reported the issue as CWBRN-19917 and was told to contact tech support.  I did this, but they have not replied except for the 'got your message' canned e-mail.  This was 10/1.
 
Here's how I described it:

1. Load project
2. Hit Play

Expect: 

•  Playback begins. Since the project is empty, you should just hear the metronome.

Actual Result:

• Run/Stop Audio engine indicator, goes out.
• Timeline does not advance
• If Run/Stop Audio engine is clicked, the metronome is heard, but the timeline does not advance. 

I would appreciate it if someone could d/l this project  and see if they get the same behavior.  I have noticed that there is a short audio file in the audio folder that shouldn't be there (there's no actual audio in the project).  If I delete the audio file, the project indicates that it will replace it with silence, but then the project is usable.
 
If it's just my system, I'm not too concerned, because I just recreated the project (it was a practice project that had virtual instruments and plug ins, so I could load it up to noodle on drums, keys, or guitar.) However, if it isn't just me, I'd like Cake to take a look because they are handling whatever's wrong very badly.
 
Thanks,
Andy

wow duplicate posts :-) first time ever .

There are seven take lanes each with a 480-tick long clip of input noise that's been slip-edited down to 30ms. I don't know why this is causing a problem, but the project works normally if you slip edit them back out to their original (or some reasonable) length or simply delete them.
 
 

Thanks brundlefly.  I know that I was messing with the new comping stuff when I fell into this hole.
 
Again, it's not so much that I care about this project, but rather that Sonar should handle fringe weirdness a bit better.
