I just upgraded today to a new version 2.1.29.
I am not sure what has happened but I am no longer able to use my left and right control to enter : ¿ ¡, etc…
My intl key board still functions normally everywhere else on my pc, and the right side alt and ctrl still work as well.
However I really need to have the left ctrl + alt input functioning for me to continue studying spanish.
I have tried everything I can think of to no avail.
