Text after "

An ASP.NET web site randomly raises this System.Drawing error:

System.Runtime InteropServices.ExternalException: System.Drawing.Bitmap..ctor (Stream stream) System.Drawing.ToolboxBitmapAttribute..cctor ()

Why? I think this is a .NET Framework error (I'm not really trying to create any image).

I found a temporary solution: Restart IIS and delete temporary asp.NET files ("% WINDIR% \ Microsoft.NET \ Framework \ v2.0.50727 \ Temporary ASP. NET files "). But when this error output is in the web-server, temp is not sufficient ...

by chance We have done this on one of our servers today. This is a known problem in ASP.NET, a hotfix for it.
