Intellij 14 weird editor/cursor behaviour

Disabling/Uninstalling the ideaVim plugin seemed to fix the problem for me. The plugin description hints that you can configure it via a configuration script in ~/.ideavimrc, which there may also be options to get "normal" behavior with the plugin installed but I haven't looked into that though because the plugin doesn't seems all that useful to me. I hope this helps other people to fix their issues with IntelliJ 14.

Disable Vim Emulator for Intellij.
