You can choose between three different basic display methods in the emitter’s first page. Just open up the menu some more to the right and you’ll see (F3).
If you have never done that (F3), you’ll notice that there are a whole bunch of extra parameters for you to use, inlcuding precision settings and other excellent control features!
Also, check your general playback settings (bottom line “play frames”…“hold”…“fraction…”) in case you’re having a funny playback behavior, it might be on purpose? 
I use “play frames” very often, but have “hold” on 0.0 of course.
