IIS Setup trying to open/save cfm files instead of rendering

Hi everyone.  I've setup my development environment to use IIS.  I can use either local i.p.'s or localhost:8500 - (regular ColdFusion).  I'm having an issue when calling any CFM file from my IIS and only in IIS.  If I go to a folder that contains an index.cfm file it will render it fine.  It's only when I actually type the index.cfm?fuseaction=xxx tht I have issues.

The issue does not exist when I do the same inside localhost:800, so I know it is an IIS issue.  Does anyone have any insight on this.  I tried Googling, but none of the solutions really help me - as it does render when it is not typed - so all of the IsapiModule and CGI references appear to be in place.

Thanks in advance.
