RemoteApp Blank Text Fields

Hi

I have an odd issue and have been unable to find a solution on the forums.

We have a Server 2008 R2 box running RemoteApp and have published our application to it. When logged onto the server via RDP the application works perfectly. However when we start the application using RemoteApp everything works apart from popup message boxes.

These forms pop up but the text field is not shown despite it being populated.

I have managed to recreate this on other 2008 servers and on 2012 so far but only through RemoteApp

The application runs on .net 4.6 

Any ideas would be very helpful

Thanks
