When I click on my drive icon on desktop, it disappears for 5 seconds, then returns. Then I try to click on Go->Computer, and nothing open. I ran a Disk Utility check and no errors came up. Just started doing that today. What the heck is going on? And I'm using Yosemite 10.10.1, didn't happen till then. Is this another bug beside WiFi issue, I read about?
