Problems W/ Logic And Midi, problems w/ logic and midi Options

hello all-
i'm running logic 5.5 and reason 1.0 on os 9.2. I set up a song running Reason with rewire into Logic as well as a few audio tracks and a few sequenced MIDI tracks going out to my Triton. When I start the song everything plays fine, but when I click on the reason screenshot to tweak the reason modules out, my triton quits responding to the MIDI (or more likely Logic quits sending the MIDI out). The audio tracks in logic play back fine whether I'm tweaking stuff in logic or in reason. Any advice? Thanks-
