</div>Quite so, especially the serial port handling. The same applies for<br>
Processing, upon which the arduino IDE is founded. You can hog a brand<br>
new computer with a 9600bps transfer.<br>

</div>I have the exact same behavior with the Uno (on archlinux). I believe<br>
it's mostly a matter of upgrading the bootloader that lies in the<br>
atmega8U. That's why I stepped back to the golden age of no autoreset,<br>
a trusty external ISP programmer, a good Makefile and a nice text editor.<br>
<br>
It seems to occur more often when the program running on the board<br>
writes to the serial port. It looks like the usb bridge and the main<br>
microcontroller are not in the same stage.<br>
<br>
Try holding the reset button, click upload and then release it. It<br>
sometimes help.<br>
