An editor reports that he lost his work when an extensive edit unexpectedly triggered the "wikimarkup" popup and - after he dismissed it - the "save" button became unresponsive. The button appeared as normal but did not react to being selected.
He was using Windows 7 and Firefox.
I reproduced this using Windows 7 and Chrome (didn't matter if I removed the wikimarkup or not), and on further investigation found that the "save" button will respond as expected after a delay.
The issue, of course, is that if this editor aborted his edit because he thought the system would not save, others are likely to think that as well.
Not sure if anything can be done to make the save button immediately responsive or to figure out why it wouldn't be or to make it apparent to editors that the option to "save" will return.
