Key strokes don't work

Yesterday I played and everything was fine.
Today, I log in and the “Attack” key or any other keys on the right hud (“stop”, “hold”) don’t work, I press “A” and nothing happens.

The only thing I can think of that happened in between was the battle.net client beta update after yesterday’s game…

UPDATE:
if anyone encounters as well.
I just did “Restore Defaults” in the options menu and it works…

You can go to the test server to see if you still have this problem

It may also be an issue with key remapping.
For example on the French version of SC, defilers use P to plague, but P is already used for the patrol command, so effectively there’s no key mapped for plague. In this particular case, I had to remap it myself.
