A client would click on a mailto tag and then Internet Explorer would spawn windows (displaying with the error Action Cancelled ) until the PC would run out of memory for the process.  After doing some research I found an article that discuses the issue and how to solve it.

A brief synopsis of the article is seen below.

When you click on a mailto: URL in Internet Explorer, multiple instances of Internet Explorer opens (more than 60 windows) with the error Action Cancelled and the mail client is not invoked. You may also see the following error:

“Could not perform this operation because the default mail client is not properly installed”

3.     Incorrect registry permissions for the mailto key.
