Dear sir/madam,
My name is Anton Leontyev, I am an international psychology graduate student studying in USA. During my studies, I have found your software (Psychtoolbox). It proved to be very helpful. However, I have recently encountered a difficulty with it. If you don't mind, could you help me with that?
The problem I've faced is drawing push buttons on screen (activated by clicks). I couldn't find anything like this in function reference, as well as in the collection of demo-experiments. If you will be able to give me any advice on that, I will be very thankful.
Thank you for your time,
Anton.
