IntelliJ IDEA 14 Copy and Paste not working with other applications

I have found the best solution yet (for me in any case). I have tried everything! Including adding and removing Keymap options. And this is actually where the problem lies...sort of.

When you have the Vim plugin installed, Ctrl + c and Ctrl + v is allocated to Vim.

To change that, go to Setting>>Other Settings>>Vim Emulation and set the Handler to IDE. Apply and OK, and Voila!

My solution (thanks to a similar issue reported with Android Studio) was to run IntelliJ as an admin.

Steps to always run IntelliJ in admin mode:

1. Right-click on IntelliJ icon in start menu search (or wherever you started it) -> Open file location
2. Right-click IntelliJ shortcut -> Open file location (yes, again to get to the .exe, not the shortcut.)
3. Right-click idea.exe -> Properties
4. Compatibility tab -> check Run this program as an Administrator
5. Right-click idea64.exe -> Properties (if you run IntelliJ in 64 bit mode)
6. Compatibility tab -> check Run this program as an Administrator
