Lost ability to use shortcut-keys in preview with new update

[August_DeGuy]

Extremely annoying bug! After updating to the newest version of Premiere, I lost the ability to use "J", "K", "L" and "Space" in the preview-window. This makes my workflow 10x slower and is really annoying. Does anyone know how to fix this?
