For what it's worth, I'm getting the same issue. I find that if I let the keyboard rest for a minute and go to type something, especially in iMessages, that the first letter I type will be doubled. Doesn't matter how fast or how lightly I hit the key. It's as if the keyboard, when waking, is sending double keypunches or is "stuttering".
I have the same exact problem as you Robert. It is like the keyboard goes to a standby mode if it is not used for 60 secs, then when I type again, it doubles the first letter typed. After that it works fine until it goes into standby again. It is an old wireless keyboard, new ipad. You are the first with this exact description of the problem that I have found.
I've been getting the same results as everyone else here, however I did want to add that it only started occurring after the last couple updates to IOS for iPad, either 6.0 or 6.0.1. I do only use the device on an iPad so can't say if this occurs on any other device, but yes, it occurs after the keyboard has been idle for some time.
Exact same issue here.
I re-use my ipad with the keyboard and notice this strange behavior.
In the past (last year) I never had this but was not on the same iOS version.
I tested the keyboard with other devices (iMac) and I don't have this issue.
Now running iiOS 5.1.1 on an iPad 1.
I'm surprised to have no official answer from Apple on this thread as this is pretty annoying. If I have to correct first word each time I think before writing (keyboard will be in idle mode) than I will simply avoid using this keyboard and by extension avoid using my iPad...
Thanks for a fast answer
Though I'm using the short Apple keyboard with my iPad right now with no problems (nor when writing an email just a few moments ago), when I goto post comments on some websites, I then get the doubling.
My 'pad is version 3, its IOS is up-to-date 6.1.3, and the keyboard is model 1314 (bought in 2009 for use with an old, hand-me-down, Mac Mini). Batteries are fresh, just installed today, in case that was the problem -- alas, no.
Since the keyboard works flawlessly on this site, works fine with numerous apps including WikiPedia, Final Draft Writer, Notes, and FileMaker Go, but does not work periodically on all the differnt sites I run to, I must conclude that the problem is not with either the iPad or the keyboard.
I would suggest the following:
a) Install fresh batteries to the keyboard
b) Fully charge the iPad
c) Turn off any other Bluetooth toy in the neighborhood -- just in case
d) Keep a detailed list of what sites and apps do or do not work with the combination
e) Try using the keyboard with a friend's 'Pad, Macs or PC's (yes, you can use the keyboard with a non-Apple system)
I'd run to the Apple Genius only as very last resort.
