Logic newbie here, while following some video tuts on logic, I try out key commands, which seem to work once or twice, but thereafter my entire screen surface (dual monitors) does a quick fade to white and back in response. For instance, hitting '0' to relocate to start gives me this flash-fade effect instead of relocating. I thought it was a system thing, maybe Quickeys, Assistive Devices (on), etc, but I can't get the behavior back to normal. I did a quick search here, but didn't find anything relevant so far... Thoughts?
