Y7 Malfunction?

So,I come across a question,and think of the PERFECT answer,an absolute home run.I type it,and click 'preview'...and it's BROKEN! What I mean is,if I typed "Eenie Meeni Miney Moe",what showed up on the preview was "Eenie Meeni Mi...Moe".It actually deleted two very critical words. I tried erasing and retyping it,I left the question and came back to it,I even thought Spell-Check might fix it.NOTHING worked!I had to abort. That's the 3rd or 4th time that happened! Has this ever happened to you?What IS that?
