Default Alice 2.2 on Terminal Server (Server 2008 R2) - 04-06-2011, 05:54 PM

I have tried to run Alice on Windows Server 2008 R2, with the intention of students using it via Terminal Server (now called Remote Desktop Services)

When running using Administrator it runs ok. However with other users, the video pane does not function correctly and does not display graphics or displays it in the wrong position. Sometimes, an error apears upon loading (shown below). The Alice folder has NTFS permissions enabled for all users. The problem also applies to users that even have admin rights but are not the actual Administrator.

Any ideas of what might be wrong?



Alice version: 2.2 02/10/2011
