This is the same issue like the one presented here, only now with a more powerfull machine. The fact that preview is generated instantaneously makes it hard to write longer answers. Sometimes, even my quad-core machine lags... Does anyone else has observed this behavior?
(I had a suggestion in the past of adding a "do not compile as I type" option.)
do not compile as I type
as an option. Sure, it is very helpful for most most people who do not know how to use $\rm\LaTeX$ well, but it is a major annoyance for those of us who are well acquainted, especially when writing a long answer. The edit grace period also makes it an appealing option in my mind. $\endgroup$ – Daniel W. Farlow May 16 '15 at 14:58
