Open Form View Designer. File Download Security Warnign Message

Question

Hi
When I open VB projects in Visual Studio 2005 and attempt to view a form view designer I have started getting "File Download - Security Warning" Message prompting a .tmp file in the location of my project.
If I close all open designers and rebuild the project I am then able to open the designers OK.
I saw a suggestion to 'restore file associations' in Visual Studio and tried this but with no success.
What might be causing this?
Thanks

Think I've sorted my problem.
I saved and read through the .tmp file prompted.
It made reference to a build of custom control I had created not being found.
I applied the latest build of the control and rebuilt the project and all seems to open OK.
