Unity 5 Copy Pasting does not usually work

When I try to paste (Ctrl V) any game object all Unity does is Vertex Snapping as if I had pressed V alone. This isn´t a problem with my keyboard because every other shortcut which makes use of Ctrl still works.
After a restart of Unity I am able to paste objects but only for a limited time. Then the bugs starts again and all I can do is Vertex Snapping.

I was having this problem earlier today. To fix it, I simply went into the ‘Game’ tab and turned off ‘Maximize on play’. Boom. Fixed. Not sure how.

To recreate it, I went to play test the game WITHOUT ‘Maximise on play’ on, then I clicked ‘Maximise on play’ while the game was running, then I stopped the play test, and started it again. Then when i was done testing, I stopped the play test, went back to the editor and tried to copy an object. Voila, nothing was copying right until i went back tot he game tab and turned off ‘Maximise on play’

If you want to copy-paste without missing it. Just copy-paste in Hierarchy window.

in the scene view you can switch between changing location based on the object or world space. if ctrl isn’t letting you paste stuff. press x once to switch how the position changin is being handles and then use control c and control v again. anyway.
