Sounds like two issues here. First rt:57 should be triggered by the spacebar being pressed. Am I understanding you correctly that, in your sample, if you use rt:57 then DirectRT is not letting the spacebar act as a valid response? But that if you use rt:any, then it's fine. Does that also include the spacebar? i.e., the spacebar will work under rt:any, but not rt:57?

If I'm getting this right, then try looking at the log data file to see what key codes are beiong recorded when you press the spacebar under rt:any. If it says 57, that will be very weird!

As for the second issue, it sounds like the cursor/matrix functionality is simply not working on your machine--esp if the cursor sample is also not working. Lets check to see if it's a mouse issue--if you use rt:252,253 will DirectRT take a left/right mouse click for input?
