Hi Everybody
I was tracking a working FW on a mega 2560. Log was flowing on its window. I detached usb cable from pc. PC went very slow, also forcing IDE shut down from Red X took 15 seconds or more. I was able to reproduce this issue.
It's not a Big problem, but something to look at one day...
Ha ha ha. I though it was a kind of tester for FW or automation test. Something tells me that you have stuck to windows XP in this specific computer which looks I have totally forgot.
Double Ha ha ha. I just noticed that when you hover over the X in Windows 10 it turns Red. If I were a first eye withness in an accident I would sure enlighten the police.
