I downloaded the demo of the app with the intention of trying the five clean-ups as proposed: I would then have bought it because it seems like a very good idea. Since then Clean app appears at each startup of my machine and the only way to get rid of it is to force it to quit. Is this to bully me into buying it? It's is the next thing to spam or pop-ups. Somebody in your team must think he's very slick. Well, please tell him or her that it may be the best app in the world, but this bad practice has just lost you at least one customer and I hope you will lose others - anyway you won't get my 10 bucks.

Never encountered this sort of thing before: just hope it won't become a fashion.

I have informed the Version Tracker team of this.
