Great dictionary, a few bugs, tech support possibly lacking

Originally purchased the American Heritage Desk Dictionary, which is very nice. Then discovered the Fourth Edition. The AHD Fourth Edition has many more words than the Desk version, plus it "speaks" pronunciations. However, very often, when I look up a word, I get a blank screen, and have to toggle between text sizes to make the dictionary entry appear. Typing a query in the search field, especially the first time after I launch the dictionary, is annoyingly sluggish. Finally, I'm disappointed that, after reporting these issues to the developer (via the email address obtained from their Web site), I never received a reply. I hope the developers will read this posting, and address the glitches I've described. At that point, the product will be worthy of a 5-star rating. It's great to be able to carry full-fledged version of a premium dictionary in my pocket! This is one of the more costly iPhone apps, but in my opinion, worth the expense. (It's also rather large. I just hope it's not TOO large for the iPhone to handle, and that the issues I've experienced are not an unresolvable consequence of its size.)

Great Dictionary

But every time I try to use it, it puts up a pop up box to get me to rate it five stars.

Almost Perfect

Dictionary:
-- The dictionary itself is incredibly comprehensive. The definitions are clear, concise, and to the point. There's simply no comparison between this dictionary and the free dictionaries based on WordNet.
-- All words have recorded pronounciation. Written pronounciation is of course also available, with the latest update including a pronounciation key.

User Interface:
-- Search is very fast, loading full and partial matches as you type
-- The History feature is great, letting you view all the words you previously looked up. You can also delete unwanted words from the history.
-- In Search mode, the 'X' button for clearing the search field didn't work very well. This seems to have been fixed in the latest update.
-- Also starting with the latest update, all words are hyperlinked, so you can click on any word in a definition to jump to that word's definition

Minor Annoyances:
-- In Search mode, the 'Info' button is near the 'X' button (including in the latest update). Sometimes the 'Info' button gets pressed by mistake.
-- Sometimes the selected definition doesn't get loaded, instead getting a blank screen. You then have to go back and choose the word again. This may have been fixed in the latest update; I haven't used it long enough to find out.

Apart from that, it's really all I could wish for in a dictionary. Well worth the price in my opinion.
