This is a known issue where the system is using the shortcuts. Turn them off in the system prefs.
Granted the pain on this release seems a bit more severe than prior versions, but I'm honestly not all that surprised. There are always interface changes or other little things that take a bit of finding or getting used to when a new version comes out, but this time essentially the entire application was re-written for 64-bit support, and a lot of how it interacts with the OS has apparently changed.
I think if you make an attempt to stick with it you'll eventually come to terms, sort of like driving a car with an automatic transmission for years and suddenly being thrust into the drivers seat and seeing a clutch pedal.
Choose System Preferences > Keyboard > Keyboard Shortcuts > Services and turn off Search with Google.
