A change in how replies are posted??

@Jason Stone (Logos) has there been a change today or yesterday in how replies to posts are handled? As of today, when I hit the Submit button, my reply simply disappears…it no longer shows up in the thread. Refreshing the page doesn't help. If I come back a half an hour later, the reply shows up in the thread. It's an odd change.
There's one other oddity, with spell-check. Now when I misspell a word, the red underline goes on and off…and if I right-click the word while the underline is off, I don't get an option to correct the word. I have to wait for the red squiggly line to come back on before I can choose the correct spelling.
???
I'll now post this and watch it disappear and hope it shows up later. :-)
