I'm a total newbie mac owner. I own an ipad and just ventured into the desktop when I received my new 27" base iMac with SSD yesterday... it's my first venture into the world of OSX from Windows and I have to say I am on a steep learning curve. I have the wireless keyboard, magic mouse and magic trackpad and yesterday after set up, I was browsing some websites and then responding to some emails in Gmail. While I was typing in Gmail or using excel, the screen kept shifting between my work that I was doing and the launcher. I couldn't get it to stop. For instance, in one email I was typing a pressed the number 4 and it flipped my screen to the launcher and didn't record the 4 in the email. I pressed the 4 again and it flipped back to gmail. I have no idea if I accidentally messed up a setting, but needless to say your help in getting this corrected would be great appreciated. I can't type with the launcher continuing to interrupt my typing. Thanks for your help!
