I am having a similar problem with a micro R3, 1.0.3 on a win7 laptop.
I can run the "AnalogReadSerial" sketch and I get the output in the serial monitor but if I run the ASCIItable sketch I do not see anything in the serial monitor.
Two years ago I had a Teensy2 (same processor as the micro) on this same netbook and I did not have this problem.
Any help would be appreciated.
Thank you,
Paul Hirst
