I'm currently using CFUserNotification to pop up a box so the user can type in their key for our game. The only problem is copy/paste doesn't work in the text field.

Does anyone know how to get copy/paste to work in the text field or know of a better alternative to CFUserNotification?

Never mind, I now have another solution working.

I'm now using CreateNewWindow to create a window, adding controls through things like CreateEditUnicodeTextControl, setting up an event handler with InstallEventHandler, and using RunAppModalLoopForWindow to wait for the user to finish with the window. It's much more complex than the CFUserNotification version, but it works correctly.
