You most likely have Touchscreen Mode enabled as stated above, therefore making this a duplicate of MC-5130. See this ticket for instructions on how to resolve this issue.

Can you confirm that you had touchscreen enabled?
The attached video shows that touchscreen mode is enabled. See MC-5130
Are you sure you haven't activated Touch screen mode in your game's settings?
