Keyboard Shift key problem

[Peabody]

This is gonna sound goofy, but I've been meaning to ask
about it for a long time, so here goes.

I do a lot of text entry on my computer, and the thing that
wastes the most time for me is when I press a Shift key,
then a letter key, and then release the Shift key, but the
letter ends up in the document as lower case. Not every
time, but often enough to really slow me down. At first I
thought that, despite 10 years of training in classical
piano, I was in fact NOT pressing the Shift key before the
letter key. But I've come to believe that Mrs. MacIntosh
taught me better than that, and that there's something
else going on.

Then over this past weekend, in talking to my brother, I
discovered that he had EXACTLY the same problem. Well, ok,
it could run in the family. But I just wonder if there is
something about how keyboard controllers or BIOS interrupt
handlers process the key presses and releases that could
lead to this effect. Or possibly even some kind of switch
bounce going on in the cheap keyboards we both use - so that
some rapidly alternating keydown and keyup codes are being
sent to the computer for the Shift key.

Well I just wondered if anyone else has had this problem,
and more importantly, has cured this problem, either through
replacement handlers or drivers, or a by buying a particular
brand of keyboard.

Any explanations or suggestions would be appreciated.

interesting - I and my better half both have the opposite issue - the
SECOND letter is often capitalized, even tho we swear we released that
damn shift key! we both have MS keyboards.

slow fingers or weak springs?

in cases like these I tend to blame the human, not the machine, tho it's
clearly less fun to do so...

There are about 10 people in our office who are experiencing the same
problem. So you are not alone...
