Description sandra pazos 2014-04-24 11:25:41 EDT 
TeeProcs.ScreenRation not working on Windows 7 and later, and up for some monitors, the cause of problem is the GetDeviceCaps HorizSize and VertiSize parameters are unreliable for physical screen measurements in Windows O.S http://social.msdn.microsoft.com/Forums/vstudio/en-US/6f06fa5e-1626-4668-b0ee-1f0d07e8d175/getdevicecapshorzsize-is-incorrect-in-windows-7?forum=vcgeneral. The problem is reproduced when enabling circled property of Pie Series and screen size, eg, 1920x1200.

One of my clients experienced this problem using Remote Access to Windows 2008 Server, Windows 2003 Server, Windows 7 & Windows XP. Normal Desktop had no problem on any of these, only when using Remote Access.

With help from Steema Support, the workaround did address the problem.
