Your post has nothing to do with the question asked by @jpsouza.
In order to avoid confusion for users who would wish to respond to the original question, I have hidden your post. Please start a new thread with your question since it is clearly asking about why some specific feature of AS 12 is not present in AS 13.
If you use spacebar to pause while recording, then to resume this recording remember to use "End" from the keyboard and check if the playhead is at the end of the recording, finally use the spacebar and continue recording.
Don't know about AS but in SF Pro and Vegas there is an 'Options> Preferences> General' option, "Make spacebar and F12 Play/Pause instead of Play/Stop". The default is Spacebar= Play/Stop. The keyboard 'Enter' key is Play/Pause by default, but as I recall, the option flips that as well. I would think AS has the same or simular option settings... Where? I do not know.

I've seen this option, but the space bar ONLY PAUSES and does not stop recording. Please, report this problem for technical support.
I'm sorry for misleading. In fact, Spacebar is only pauses, I don't know why, but I thought it was about the continuity of the recording. When we select the option mentioned by @rraud, Spacebar paused but the playhead stands at the end of the timeline (as in the case of using Enter). And then pressing again Spacebar - starts recording from the end of the first recording sequence. If you want to Stop recording, you must use "ctr + shift + Enter" or "ctr+R".

In previous versions, the spacebar stops recording. Magix spoiled Sound Forge.
