Weird error message within Delay Discounting Task (short term)

Hi there, when I use the delay discounting task (short term) and participants click on the letter B shortly before it starts to blink, they get the following error message. If you click on "close program" the task continues. There is no error log within inquisit and for the letter A this instance does not occur. I would appreciate your help very much. I attach a screenshot of the error and the paradigm I use.

AFAICT the problem is causes by the longer /pretrialpause (as per values.bdelay) in the "b"-trials. Inquisit uses the pretrialpause to prepare stimuli (load them into memory, etc.), but the long pause appears to throw things off (it's certainly a bug).

Choosing an alternative method (avoid /pretrialpause) to implement the delay should be sufficient to prevent this from occurring (see attached file).
