Hot on the heels of the last post, another misplaced word, except I am not sure quite what the writer meant.

"Microsoft has developed BlueTrack - the world's most advanced tracking technology - and added it to the new Explorer Mouse. Remarkably, it works on virtually any surface...

BlueTrack technology works by emanating the light off the surface it's moving over. High-angle, imaging optics generate an exact replica of the surface, enabling it to respond instantly to your hand movement, wherever you are" - from a Microsoft business mailing

To emanate, in the sense I think they mean, means to radiate or send out - as in "the oven emanates heat when the door is open". But I am not sure what the marketing genius who wrote the above means: I don't think you can emanate off anything. Suggestions on a postcard please.

And from the same pages "Welcome to a world of easecheese, with BlueTrack™ Technology. Only available from Microsoft, this new tracking technology allows you to use a mouse on virtually any surface" - sorry, I made that up
