I am using Telerik Controls Q12013 and it is working fine in default (100%) OS but I am facing Layout problem RadMessageBox with 125% OS zoom in Windows 7.(Desktop [Right click] > Personalization > Display > 125% Zoom). I am facing while using Theme "VisualStudio2012Light", "TelerikMetro", and "TelerikMetroBlue" but its working fine in default Office2007 theme. I have attached some images for your better understanding. Kindly look into this issue and I am waiting for your reply.
