 Hi!
 
 Not sure what happened with the title, sorry for that.
 
 Since reporting this issue, I managed to create a fix that works on my
 computer.
 
 It seems the button code was wrong for my computer, not sure if there
 is a generic solution to the issue.
 
 I was able to figure out the correct code through debug statements.
