Regarding the page crash that I reported to this topic (Dec. 18th), I found when every time I modified the source code down below the screen, and then I press Save button or Ctrl-S, your APP will re-align the tag into it's location that your app preset. I actually like this function since it make the code clear and easy to read.
But this feature might also cause the codes been flushed out and all gone with only left the blank. I found this bug is not happened every time, but with very high "hit rate" happened, let's say 4 or 10 times. It doesn't need those complex tag, even just a simple tag like "br". I guess that could be some bug inside your tag realignment feature.
I have screen copy this time, and this situation actually happened twice during my operation for screen copy.
The file 10-27-55 is the crashed screen, and the 10-28-32 and 10-28-45 are the operation log.
It's holiday season there, so just take a good holiday and not hurry about this. Happy New Year.
ps. I am new user and can only send you one pic. send them through later.
