Copy Paste issue HTC Desire C

Hello new poster here I hope someone can help me.
I used to have an older model phone and never had any problems copying and pasting data from the phone to my pc at home using an RDP app.

I now have an HTC desire c which is a great phone but I can't copy and paste any more to my home client.

I copy the text but when I run a ctrl - v using pocket cloud nothing happens.
This worked fine with my old phone.

any help would be appreciated.
