When I first start typing in the Reply box, everything is fine. Then, a few minutes later, I see a little message that says "Draft saved" or something like that. As soon as that happens, typing b e c o m e s. W a y. T o o. S l o w. Like literally seconds elapse between keypress and the letter appearing on the screen. This happens in IE 11 Modern on Win8.1, and also on Firefox 20-something on Ubuntu 14.10. So I think it's a problem with how this feature is coded. Is there at least any way to disable this? Otherwise, typing long posts to explain mathematical finery will be too excruciating to bother with any longer.
