ctrl, alt, win + key combination doesn't work with 2x RDP on 4.1.2

[Google Code Exporter]

Dear Sir,

This project is simply awesome! Exactly what I looked for.
Unfortunately, I have this issue.
It works with notepad (I tested ctrl+c), but doesn't work with 2x RDP
Bluetooth keyboard works with 2xRDP flawlessly.

What steps will reproduce the problem?
1. start 2x RDP
2. create a connection to your PC over remote desktop
3. open notepad in remote OS
4. type something
5. highlight it using mouse (shift and arrows doesn't work either - I could 
create another issue report)
6. press ctrl+c
7. highlighted area will be replaced by c and no information in the copy buffer

What is the expected behavior? What do you see instead?
on a step 7 I expect to have highlighted text unchanged and be copied into the 
copy buffer.

What version of Hacker's Keyboard are you using, for example "1.37"? 
1.37

On what phone or tablet?
Samsung Galaxy Note 2 with 4.1.2

I think you created this keyboard to use RDP. In a meanwhile, could you please, 
suggest which one are you using with your keyboard?

Thanks.
