There are programs that are developed for Windows OS, that don't allow Clipboard functions. Like the Command Prompt from Windows (which doesn't support the Paste process through the key combination Ctrl + V) the DwimPerl application doesn't support this kind of actions. In this matter, you can always use a third party tool that will allow you to perform copy / paste actions. In this matter, I suggest to look into the Software Informer's database for a solution.
