Repeated Compilation Errors - References

I get this error frequently after a rebuild and attempt to view a page:

Code:

Compilation Error
Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.

Compiler Error Message: CS0006: Metadata file 'c:\winnt\microsoft.net\framework\v1.1.4322\temporary asp.net files\myapp\c7058d65\1eb31c7\assembly\dl2\c0a83075\0033f047_0ff7c301\somereferenced.dll' could not be found

Source Error:

The error deals with references I have set in the project. It seems to be missing the temporary dll cache item. If I remove and re-add the references it seems to go away for awhile but comes back later.

Or if I rebuild the solution and try to run again then the error goes away.

This is very annoying to have to do every time I want to view the page. I just wondered if anyone else has seen this.
