A check with ATI Radeon X550 shows my drivers are up-to-date.
A Dxdiag shows all three buttons as enabled.
I used a progr called "Drive Checker" It found obsolete drivers for the ATI
X550, Sound Recorder, and Microsoft. To download I first need to purchase
the progr. Idid not, for I don't trust these offers and cannot afford it
anyway.
This seems to be an exercise of futility. I will have to live with it.
Thanks for your extensive patience and help.
Nurmi.
Do not use driver checking programs. They are a waste of money.
It could well be an exercise in futility, but that is what
makes computers fun. We cannot let the computer win at this
game

reinstall all the software - but that is admitting the computer
has won.

Try Control Panels

Try moving the slider back one position from full acceleration.
See if the symptoms change.

My own computer has a problem with acceleration, but it is
triggered by playing a game and alt-tabbing out of the game.
(The game continues to run in the background, something I
do when using the machine for more than one purpose at the
same time.)
When I attempt to move windows around the screen, they slowly
redraw, as if the acceleration is disabled. Fortunately,
I have figured out what triggers it, and using System
Restore, and returning the system to a previous day's restore
point fixes it. If I go into the Display control panel, make
changes and save them, that seems to cause it. I'm using the
video driver that was packaged with WinXP SP3 (not a downloaded
ATI driver), and I think if I changed the driver, it would
likely fix it. The reason I've left it, is for a time when I
discover another way to cure it (other than System Restore).
