Lately, for no apparent reason it would seem, when I open the Design view of the main form of my project, I get a warning message saying, "To prevent possible data loss before loading the designer, the folowing errors must be resolved:" The only description of the error is "DesignTimeVisible", which occurs at line/column (0,0). The call stack reads:

at System.ComponentModel.ReflectPropertyDescriptor.SetValue(Object component, Object value)
at System.ComponentModel.Design.Serialization.CodeDomSerializerBase.DeserializePropertiesFromResources(IDesignerSerializationManager manager, Object value, Attribute[] filter)

I'm working in Visual Basic 2008 Express Edition, and the project is a simple database project, using SQL Server Compact Edition. I can post code, as requested.

Thanks in advance,

David
