hey david,
to answer to your questions:
- stdout.txt is empty
Are you running any other programs that use the serial ports?
I'm not sure but I don't thinks so, because the problem started appearing after a while: I had safely exported a few times before the problem happened. at the beginning I thought the problem was in the code I was uploading into arduino, I thought I found some sort of fork bomb that crashed my computer. But then I tryed to do a simple hello world or led blinking and it crashed as well.
I tryed to reinstall the arduino-00002 folder from scratch but that didn't work either, the pc keeps rebooting. It seems as it set some nasty global variable or somenthing else that tells it to reboot
Have you installed cygwin on your machine?
cygwin1.dll is inside the arduino program folder arduino-00002... I haven't done anything else with it.
searching on my pc there are other cygwin1.dll under several versions of the old ide and wiring folder as well...
there is only another one cygwincompiler.py (python) under open office but I don't think It has anything to do with it

any other idea?
what is cygwin all about it?
The export button simply recompiles your code and runs uisp
does this means that we can avoid clicking on the compile button? that the export button does it automatically?
thanks for the help
