There have been times (not all the time) where I record a vocal and you see the WAV drawing and as I press stop, it disappears as if I never recorded a thing.
Anybody else ever seen this, and what could cause this?

I've seen this happen when the wrong audio drivers were installed.

I am seeing this from time to time. Very weird, and sometimes very annoying. Loosing a good take like that. Has nothing to do with "wrong drivers" as I am using the correct ones on a Roland Octa-capture. Recording just dissapears as soon as i press spacebar to stop.
I have no idea what causes this.

I've had it happen....

I've seen this happen when there are Punch In/Out points active, maybe only for a few ticks but enough to prevent recording.
 
It LOOKS like Sonar's recording but in fact, isn't.

Yes I have had this happen. Not all the time but usually on the first recording after opening SPlat /CbB. I usually do a quick dummy recording to start with just in case.

I use punch in/out a lot but not usually at the start of recording.

Try deleting everything in the Picture Cache folder.

Yes, punch recording appears to record the whole track but does not keep anything outside the punch points.

I am using punch recording for its intended purpose i.e. recording specific parts within a track that need re-recording whilst leaving the rest untouched.
 
The "recording disappearing" I am talking about is like dahjah details. Punch is not in use and it generally happens once at the start of a recording session. You see the waveform as it is recorded but when you hit stop there is nothing there. Record again and all is fine.

Unless you are also the OP, this is irrelevant.

Punch recording can cause the same symptom the OP describes. Your issue may be different. There are other suggestions in this post and similar threads you may want to research. Just because you claim to be using punch recording as intended does not mean the OP is (unless you are posting using both IDs).
 
It would be helpful for the OP to revisit this thread.
