How about an on screen keyboard is that any better.
Impossible. That'd require buying a monitor that allows the user to do that.

  You don't need a touch screen monitor to use an on screen keyboard .

You can use a mouse-cursor to operate the onscreen keyboard that comes with windows 8, see the microsoft link ... http://windows.microsoft.com/en-GB/windows-8/type-with-the-on-screen-keyboard  which shows a video of the on-screen-keyboard, ( about 1 minute into the video ).

Not suggesting you use the on-screen-keyboard permanently , it's just a way of testing if your keyboard problem is specific to the wireless keyboard , if that is the case it won't occur with the on-screen-keyboard if you use a wired mouse or touch-pad to move the cursor to press the on-screen keys.

I see. I was unaware of that. Thanks.

Bluetooth is dodgy at the best of times, particularly in a heavily bluetoothed environment or in the presence of cell phones. In the case of a wireless keyboard I suspect there is a lot of handshaking and parity checking to ensure that the computer is displaying what you think you wrote, so it can be very slow in the presence of noise. We have interesting problems with "wireless radiography" where the image receptor is trying to shift several megabytes to the display whilst the surgeon (it's always a surgeon) is trying to book his golf appointment.

Or does the text appear in chunks? That would suggest some other function is taking priority within the computer. HD porn transmissions from the Vatican can load the RAM and damage your mind.

I get the impression that you are in the medical profession, Do you find it frustrating and wish that like we who only work with computers you could do a complete reformat and start again on the patients ?

Medical physics, actually.

Not frustrating - at least not in the labs and clinics, though admin is another matter. I find the processes of life, disease, injury, healing and death very interesting. If I thought we could just switch off and reboot when things go wrong, I'd lose the thrill of the chase and the intellectual exercise of balancing risk and benefit.

You can rework a hip implant if it malfunctions, and the equation is fairly straightforward, but should you rework a functional cochlear implant because the next generation has a superior performance, or because the external hardware is obsolete? Indeed given the probability of obsolescence - I am older than the transistor, never mind the integrated circuit, and I was well into my thirties before digital signal processing became feasible - is it ethical to implant an electronic device in the cochlea of a profoundly deaf 2-year-old?   

Rebooting the brain, however, does seem to work. I'm presently intrigued by the story of a woman whose vestibular system was destroyed but has learned to balance and walk again by some kind of reprogramming, intially by an accelerometer, and now it seems by recognising neural baroreceptor signals.   

None of which is helping Peter improve his typing speed!

I'm trying to fix it using this: http://support.microsoft.com/kb/2665220#LetMeFixItMyselfAlways

However it says:
Quote
For 32-bit Internet Explorer on 32-bit Windows or 64-bit Internet Explorer on 64-bit Windows
installations:
...

For 32-bit Internet Explorer on 64-bit Windows installations:
...
How do I determine which of these I'm running?

It also says
Quote
3. Create a new DWORD called
iexplore.exe
and set its value data to 0x00000000(0).
How do I do this?

It also says this as well
Quote
If after creating the registry key you want to re-enable connectivity events, set the value for
iexplore.exe
to 0x00000001(1).
Again, how do I do this too? Thanks.

Thanks for your help everyone. It's been a pleasure. :)

You're asking how to modify the windows registry , which is critical to the computer's operation : if you modify the wrong thing in the registry the computer can become totally inoperable.

It shouldn't be necessary to modify the registry to solve your problem.
Modifying "iexplore.exe" relates to Internet Explorer internet browser,
any modification there won't fix problems encountered on other programs like Microsoft word-processor.

If you must modify the registry, the tool to do that is regedit , but IMO do not change anything in the registry : risk without benefit in this case.

That your computer is not paying enough attention to the keyboard sounds like it is busy doing something else, if that is the case it should show up in "processes" tab of task-manager as a process using a lot of CPU , ( say constantly at about 50% CPU even when the  computer should be idle ). 

If the CPU is not running high then it's probably a problem specific to the wireless keyboard , this Microsoft page looks relevant ...

Thanks, RD. I'll take your advice and leave it alone. I don't want to mess with that stuff for fear of really messing it up.

Have you checked the settings for the keyboard "typing stroke delay"(basically speed and repeat speed-hold down) in the control panel for the keyboard. You may need to first install the keyboard driver for the OS to properly understand it, as much the transmission terminal.

I am sorry to butt in but was just wondering, PmbPhy what is your hard drive? Is SSD or the older type?
