skipping double letters

[Jeff]

I'm using XP MCE on a Toshiba notebook PC.
I keep having a trouble of letters being skipped when I type rapidly.
This is most apparent when I type a double letter (letter might come out
leter), but it sometimes happens in other cases if I type real fast.

I've gone to the settings for the keyboard and tried different settings
unsuccessfully. At present the keyboard properties are set as follows
for "Speed":
Repeat delay: set to closest to Short
Repeat rate: set to closest to Fast.

Have I got the settings wrong? Is there somewhere else I should look?

Thanks.

Jeff

You should also check if the Filter Key is on.

1. Click Start - Control Panel
2. Open Accessiblity Options
3. Uncheck Filter key

Hope this help, let us know!

It was off.

Does it skip letters in every application or just MS Word and Internet
Explorer? Had you recenlty installed any application after which it is
causing the problem? Uninstalling it may solve the problem? If you have
recently installed IE7 then it could also be cause of problem.

Let us know!

A few thoughts:

- An interrupt, or two, is dedicated to seeing kb action, and there's a
buffer for keeping up to 10-256, some amount of keystrokes stored. I
suspect some operations are using so much process time that the
keystrokes aren't being stored and recorded.

- Look in Task Manager to see what process is using so much CPU time.
It could be malware.

- As a test, in System Properties, Advanced tab, Performance Settings
button, click the "Adjust for best performance" radio button. See if
this helps. You may not like these features being off, but it's just a
test. Under the Advanced tab, change to "Background Services" under
Processor Scheduling.

Hey, it could even be a keystroke-logger that's sending the letters to
headquarters!

Thanks Elmo. I have no malware. I keep a very clean machine and check
regularly for viruses, Trojans and malware.

"System Idle Process" uses the most at 98 CPU. Everything else runs 1-4
CPU.

Can that buffer be increased?

Problem is mainly when I use Word.

Thanks. Jeff

I'd suspect you may be too fast for the keyboard itself. Try a USB
attached one and see if that cures the issue. You may have to "release"
the key a little longer on the laptop keyboard.

I would try an external keyboard. Also try a hardware group for better
suggestions.
