Dear Mario,
Thanks for your help.
I downloaded and installed the ATI drivers from the
website and Psychtoolbox ran on Windows Vista.
I'm still having some syncronization troubles (see
the information below)
Best regards
Luis

WARNING: Couldn't determine end-line of vertical
blanking interval for your display! Trouble with
beamposition queries?!?
WARNING: Detected end-line is 798, which is either
lower or more than 25% higher than vbl startline 800
--> Out of sane range!
PTB-INFO: OpenGL-Renderer is ATI Technologies Inc. ::
ATI Radeon Xpress Series :: 2.0.6956 Release
PTB-Info: VBL startline = 800 , VBL Endline = 798
PTB-Info: Beamposition queries unsupported or
defective on this system. Using basic timestamping as
fallback: Timestamps returned by Screen('Flip') will
be less robust and accurate.
PTB-Info: Measured monitor refresh interval from
VBLsync = 16.693278 ms [59.904352 Hz]. (50 valid
samples taken, stddev=0.038557 ms.)
PTB-Info: Reported monitor refresh interval from
operating system = 16.666667 ms [60.000000 Hz].
PTB-Info: Small deviations between reported values are
normal and no reason to worry.
----- ! PTB - WARNING: SYNCHRONIZATION TROUBLE ! ----
One or more internal checks (see Warnings above)
indicate that
queries of rasterbeam position are not properly
working for your setup.
Psychtoolbox will work around this by using a
different timing algorithm,
but it will cause Screen('Flip') to report less
accurate/robust timestamps
for stimulus timing.
Read 'help BeampositionQueries' for more info and
troubleshooting tips.
