I have just encountered this weird problem: I suddenly need a 3rd key to make zerglings. I use the core. I did not install a patch and did not changed my language setting on the keyboard as far as i'm concerned. It just seemed to happen spontaneously.
In the old situation I could press 'j' (hatchery button) and then ';' to create zerglings.
In the new situation I now have to press 'j', then 'k' (larva button) and then ';' to make zerglings.
With all the other zerg units, it still works just to press 'j' and then their specific hotkey.
What is causing this extra key to produce zergling? And more important, how to restore the old situation?
Thanks!
