Laaca: I'm not 'blaming' BP or FreeDOS - I'm trying to understand why I'm getting the error. I am quite prepared to accept that my app design and implementation is at fault but, after hours of poring over the code, I can't see anything which is obviously at fault. I have been very careful to Dispose of any structures created by using New once they have served their purpose.

Indeed, this may well be the problem. At this stage, if it is the problem, I'm not sure how to overcome it.

Thanks.
