How to REMOVE after uploading into mBlock Arduino board?

#1

Assume I have completed writing a program using the default mBlock and now plan to upload to Arduino. It works and now its in the mBot.
Q1: However, when I want to REMOVE it how do I do it? The problem I faced is post upload mBot works continuously running my program!! Switch on/off on board didn’t work, so much so I had to reset the mBot.
Q2: Other than the advantage of reducing the serial lag due to network, what other advantage does it give?
Q3: I am on Windows 10 and I see the code on Arduino. However, when a click on Edit with Arduino IDE a splash screen appears and then disappears. Nothing else comes up.

Read this page, especially the guide pdf document about the different options to run code: http://learn.makeblock.com/getting-started-programming-with-mblock/

Q1: just replace it by another program. If you want to have the default program back, see the guide.pdf.

Q2: mBot can run without a PC or mobile device.
