Ok so you can give this a go. Hoping its not too much hassle to setup...
If you install Virtualbox from here
https://www.virtualbox.org/wiki/DownloadsAnd download this exported instance I've created
https://static.feral-heart.com/FHonReactOS.ovaWhen you open the instance file it will ask to open with Virtualbox.
When asked choose to Reinitialise the network cards.
Then open Virtualbox and you will see the FHonReact Instance that you can start.
You should now have a system with FH on it. Run FH in there.
Now if you use the onscreen keyboard from your main machine the game shouldn't loose focus. Which should make using it far easier.
Let me know how you get on.
