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.

RE: skipping double letters

 

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!

Re: skipping double letters

 

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!

Re: skipping double letters

 

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

Re: skipping double letters

 

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.

Re: skipping double letters

 

 

I have noticed that double letters are removed when I call SendInput to

simulate keystrokes. When simulating keystrokes from the thread that

runs the active window, I have found that a call to the dot NET method

SendKeys.Flush() after every keystroke eliminates the double letter

removal problem. When done in other threads it has no effect. This

makes me think that there is something wrong in the event processing of

the window itself. This probably does no real good in solving the

problem, but it may help in eliminating a variety of things that are not

the problem.
