I can't find another post on this topic, so am writing my own to see if anyone else has the same problem. I just got the Curve 8300 (ATT, enterprise) and am having a major issue where the Curve misses on letters typed quite frequently. I type fairly quickly on the keyboard, and at the end of a sentence many letters are missing. I hear the "click" from the button, but nothing shows up on the screen. Typing slowly works, but is a pain. Have used Blackberry and Treo for many years and never had this problem. Any thoughts?

Welcome to the forums.

See if this will help: Click on Options (or Settings then Options) -> Screen/Keyboard. There is a setting for 'Key Rate'. Set that to 'Fast' and see if it helps.

Like anything else, you will have to get used to it and you will. I have the 8800 which has larger keys but no spaces. At first, I was having your experiences. Now, I type faster than I would on a PC.

I have the exaact same problem, I'm quite a quick typer on my curve, and some letters just don't "show-up".
I did resolve a bit of my issue - gtalk was always running in the background, and was eating my bandwidth/ device memory - just by closing it I am 80% back to full speed and pleasure of my curve.
