    Question NoSecurityChanges flag error when adding items in ToolBox

    Hi, I try to add .NET items in my ToolBox (choose items...) by browsing. When I click Open, I get this message: "The security state of an AppDomain was modified by an AppDomainManager configured with the NoSecurityChanges flag." I work with VB 2010 and Windows 7 - 64 bits Thanks for help
