Razer Naga + Windows 7 VMbox on Macbook

[gzvt]

Hello, I have Razer Naga mouse that allows using Keyboard Shortcuts. I have CTRL+C button on it that works perfectly on my mac, but when I try to use Shortcuts in my guest VM Windows 7 it print just "C" sometimes and sometimes it works correctly. Same with all Shortcuts like CTRL+V etc... I have no idea how to fix this. Any advice and suggestions will be greatly appreciated, thanks

My OS Is Sierra 10.12.6
I have Guest Additions installed
My Guest OS is Windows 7
My VMBox is Version 5.1.28 r117968

I did check how Keyboard Shortcuts works with my Server OS (Windows Server 2012 R2) + Guest OS Windows 7. And I discovered that it works perfectly with Razer Naga and Keyboard Shortcuts. The problem is only on my mac.

The host may have a Razer Naga mouse, but the VM does not. The VM has a standard PS/2 mouse.
