MacBook Pros: First typed letter missing when typing in text fields; Apple acknowledges

Apple has apparently acknowledged an issue with some MacBook Pros where the first typed letter in a new text field is sometimes missing. For instance, when filling out a Web-based form, typing the word "dog" in an address field may result in only "og" being typed. A description from one poster to Apple's Discussion Boards reads (in a thread amusingly titled "ELP! - first letter always missing!"):

"Anytime I position the text cursor into a new field (ie google search, a new text document, saving, spotlight, you get the picture... anywhere!) and type, the first letter doesn't register"

A poster to the same thread reports receiving confirmation of the issue from Apple, specifically:

"This is a follow up to Bug ID# 5365684. After further investigation it has been determined that this is a known issue, which is currently being investigated by engineering. This issue has been filed in our bug database under the original Bug ID# 4333743."

Other users, meanwhile, are reporting sporadically missing letters during normal text entry, e.g.:

"I have ried all of them... Note he t is missing in many o the first letters and the f is also missing. I thought it was me so I sent it back. Apple replaced a few things and sen it back"

Adjust key repeat settings Some users have been able to mitigate this issue by adjusting their key repeat rate settings in the Keyboard and Mouse pane of System Preferences. In particular, setting the "Delay Until Repeat" to very short or off has resolved the issue for some.
