Confused about how to play back Spec previews in real time

So I have Nucleo Pro 2.0.0.138 and the Spec preview is working just fine. It renders my work area, everything is green, yippee, hay hay. When it's done, if I hit the space bar to play, the render doesn't play back in real time (this sequence is SD 29.97 and it plays back @ 18 fps or so). If I hit the AE Ram preview, it plays back at full speed, but it does some sort of AE Ram preview first before playing and it also ignores my work area (i.e. the RAM preview plays beyond the work area). What's the proper way to play back a Spec Preview?
I am on a MacPro 8 core with 16GBs RAM, fast drives, and a Kona card v5.0 drivers.

Try using the numeric keypad '0' to start and stop a RAM Preview (or scrub the timeline if you just need a piece of it). RAM Previews should respect the workarea.
Spec Preview simply fills and keeps topping up the preview frames - the playback is After Effect's responsibility. Sometimes there are frames that aren't filled in (such as blank frames) but the preview quickly figures those out.
The spacebar starts a standard preview which will use disk caching if it runs out of memory (this disk cache is AE's and independent of the Nucleo cache).
A RAM Preview keeps everything in memory (which if the preview is too large means part of the green bar will disappear or move about as the preview plays back).
Remember the RAM Preview is controlled by the settings in the Time Controls panel in AE. Nucleo will observe preview settings based on the chosen item in the "Fast Preview Options" setting in the Nucleo menu. See the PDF User Guide (in the Nucleo plugin folder) for details.

Thanks, Chris. Something was messed up with the work area thing. A preferences trash cured it.
Things seems to be running just fine, except I am getting frequent "Nucleo Pro has encountered an error, click here for details". i click and it shows me nothing but the regular log saying when nucleo has been started for the day. The thing is, Nucleo seems to keep running and working like there's really no error so it doesn't bother me.
