Why can I see my subliminal stimuli?

Jiff128, Ssmith,

What versions of DirectRT are you using, i.e., 20xx.x.x? In cases where it worked well using a prior version, was it the same same machine? If so, what version of DirectRT was that (if you can recall)? Also, if you run some of the various samples that come with DirectRT (especially ones from the first few folders), do you get similar variance in the display times?
