No-op puzzle looses shift-arrow input
This bug has been around 'forever' in the no-op puzzles (today it annoyed me a tiny bit more than usual )
As the title says: At a certain point, usually somewhere halfway the puzzle, one cannot input the operator using the shift-arrow combination anymore. Only way to restore is to refresh the page.
I'm using Opera atm, but the bug existed in Firefox & Chrome too.
Cheers & keep up the good work
