DrawDots bug

1
Hi all,

I recently updated to the latest current version of psychtoolbox and
realized now I cannot draw a circle dot by DrawDots command anymore.
Here is the syntax in my program:

Screen('BlendFunction', w, GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA);
...
Screen('DrawDots', w, [center(1) center(2)]',LEDradius,[255 0 0]',[],1);

Now it always draws a square dot instead of a circle... I am really
frustrated with the problem so please, any help is much appreciated!!!

Thanks!

Actually I found out the problem: It is because of Bootcamp 1.3 with
it keyboard control program has taken over the alpha-blending screen
control in Windows. Eventhough I still have no clue how to solve the
problem, at least it points out that the psychtoolbox DrawDots
function is not buggy.

Thanks.
