Sorry to bother you with this off topic subject but I've run out of
ideas.

Ever since I installed Vista on a laptop I have a weird keyboard
behaviour. When typing in text, the caret will sometimes jump to the
position of the cursor and text entry then continues there.
It happens in Delphi, but also in Wordpad and Word.
I can find no systematic. It seems to happen more often after some keys
than after others, but there is no clear pattern.
I've installed the latest drivers for the computer. Unfortunately I
installed an OEM version of Vista. Can get no support from MS or Dell.
Since it is a laptop I can not change the keyboard.

Anybody any suggestions ? If not a solution, then maybe an explanation
for this behaviour.

Perhaps as you're typing your thumb or palm is brushing against the
touchpad below the space bar. I think most laptop BIOS configuration
programs let you disable the touchpad altogether. The mouse control panel
might have some way for you to adjust the sensitivity. I think some brands
even have a feature that tells it to ignore events from the touchpad while
you're typing.

So simple! (But I must say that my very first reaction to your answer was:
come on Rob, I'm not that stupid.)
I've never used a touch on the pad to position the caret. Always do that by
clicking the left pad-button. So I have not been aware that brushing the pad
can move the caret to the cursor. And that is indeed what has happened. It
explains why certain key strokes seemed to trigger it more than others: the
keys in the middle of the keyboard on the upper rows. They force a thumb
over the touch pad.
I sounded such a stupid thing. Yet, I'm very glad that I've asked and that
you responded so quickly and adequately. Thanks a lot.
