is there a way to 'crop' the region into just the frame I am looking at?!
There is a key command called "Delete MIDI events Outside Region Boundaries." You need to assign the command -- there is no default for it.
Also, if ever you wonder if there is any MIDI data outside region boundaries, "Set Optimal Region / Cell Lengths Rounded by Bar" will expand or contract the region borders accordingly. I use this a lot to tidy up the Tracks area and check for overlooked data. If the last note of a region extends to the next bar even by one tick, this command will expand the region to include the full bar.
A companion key command is "Set Optimal Region / Cell Lengths Rounded by Note Value."
