Hi, I'm unable to delete a mapping in the service window. I get the delete icon when I click the mapping connecting line, but when I click the delete icon, nothing happens. Not even anything in the JS console.
I'm using Version "44.0.2403.157 m" on Windows 8.
Image attached.
I've had to switch browser versions to get it to work on occasion (i.e. I normally use FireFox so when this occurs I switch to Chrome.)
Thanks Crystal. Firefox worked fine.
Face firmly in palm for not trying that earlier 
Andy
