Google Chrome Frame IE Add-On Changes User Agent Sometimes While Not In Use

I was having session key troubles recently and finally tracked down the problem...The Google Chrome Frame Add-On for IE 8 changes the user agent under certain conditions; most notably the first page load or if you refresh the page by hitting Enter on the url bar instead of the Refresh icon.

In short, it either needs to inject this crap every time or only when I am using a Chrome Frame.

Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.0; Trident/4.0; SLCC1; .NET CLR 2.0.50727; Media Center PC 5.0; .NET CLR 3.5.30729; InfoPath.2; .NET CLR 3.0.30729)

Changed to this

Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.0; Trident/4.0; SLCC1; .NET CLR 2.0.50727; Media Center PC 5.0; .NET CLR 3.5.30729; InfoPath.2; .NET CLR 3.0.30729) chromeframe/5.0.342.0

Needless to say, I uninstalled this crap, but not before it ate up hours of my time tracking it down. I've lost a little faith in Google's goodness today along with those hours of time wasted.
