I am not sure if you should be doing that.
I am assuming that the POPUP you mention here are the security prompts that IE throws up, asking you if you want to continue or not.
These prompts can be turned off in IE security options, you could add a prerequisite to your scripts to reduce the security settings of IE, which then will turn off al prompts.
I know this is not a direct answer to your query, but I guess this gives you a new perspective.
