Access Sage 50 Payroll over remote desktop

SUGGESTED

Afternoon

I have a user who has Sage50 payroll on her office PC. 

In order to be able to work from home she has a laptop that allows remote access back to her office PC using Remote Desktop Connection

However, while every other application on her PC looks the same over the RDC, including Sage 200,   Sage 50 Payroll seems to shrink in size so that its barely usable.

I have tried increasing and decreasing both the Scaling and Resolution on the laptop, but whatever I do seems to make it worse.. 

If she connects using Splashtop it all looks fine.

Any ideas as to what would be causing this???

Thanks

Tania.
