Can any one please tell me whats wrong with this piece of code.
When I press button 1 - everything is good. I want to press button2 - to stop the process started by button 1 and do an another process. I am unable to do it - MY GUI is going irresponsive.
You are welcome to edit the serial communication with PRINT statements if you like in doit and doit2 functions.
Please dont comment about how I made the GUI - it is just a quick example. Please comment on why I am unable to pass the pill2kill - when I press the button 2. And why my GUI is going to irresponsive state.
