Query: Unusable in HP WebOS "app"

I have the Kindle App for my HP Touchpad. I purchased and downloaded this dictionary. When I initially opened the dictionary I thought my device had "frozen". Now I believe it took so long to load that it only appeared that way.It is unusable. Each page loads one-at-a-time and very slowly. The A-Z index does not work and, if I search for a word, it takes so long that I've never managed to complete it.I think this might be great for a Kindle, but think carefully before purchasing it for other devices with Kindle "apps".I will check to see if I can get a refund.
