Access is denied: 'Microsoft.Web.UI.WebControls'.

[Guest]

Recently I am getting this error randomly while working with visual studio
..NET 2003 on a C# project and browsing my application. Everything comes to
normal after rebooting. Can someone help on this? The following is the detail
error message:

This is happening to me to. I've fixed it with a machine reboot or
dereferencing the control
but that doesn't work everytime.
