I have recently installed IntelliJ 12 and have noticed that I have to always do a double click to perform common operations like executing a menu command or closing a tab by clicking on 'X'. My team mates, however, don't face the same issue, so I'm inclined to believe that it is a configuration issue.
Has anyone faced this issue before? I have set the "Autoscroll from source" option that now opens files with one click. I still have to double-click on Menu items.
