Ok, I've got issues here with arduino and processing.  I have about 70 different sensors, and all of them are producing the same errors.  It happens whether I write the code or use examples.  changing the baud rate in the two programs does nothing.  so basically, here's the problem:  the serial monitor in Arduino is fine, sending totally perfect data, right?  until I open a processing sketch, then my stream of data in the arduino serial monitor goes haywire.  for instance, a stream that looks like this:

83
83
83
83
84
84
84
85
85
85

will suddenly go like this when processing takes over the serial:

8
   38383
8888    333
3  8     3333333

            4

44448888   8584

any ideas???  please help
