We are getting this at our firm as well (Windows 7 / Office 2010 32-bit). At first, it seemed controllable by insuring the Screen Resolution was set to Detect the Dell Display rather than the default Generic Non-PnP Monitor (though a KVM switch made that not stick). Now I see that editing the normal.dotm from Calibri font to Times New Roman causes this as well. Any further information on this? Did you ever receive an answer?

Thank you.
