I'm not sure how to fix this properly, but killing the Dock (forcing it to auto-restart) stops the quicklook pane reappearing. Just run this from a Terminal window: killall Dock
Yes, this is annoying! Many forum posts mention the fix done by defaults write com.apple.Dock workspaces-auto-swoosh -bool NO with restarting the Dock afterwards: killall Dock This, however, didn't work for my Yosemite 10.10.2 installation. Just thought I mention it here until some real answer comes. One of many sources.
I was having this problem too. I tried moving the mouse down to the bottom of the screen and then pulling down again and that worked. Don't ask me why it has to be this complicated, I think its a bug. Hope This is Helpful
If none of that works, open Terminal and enter killall Dock.
