I think you are right. It is the PDF loading that appears to be 
causing the crashing. I think your guess on the previous call to the 
Thread completing when a new PDF should load is absolutely the 
problem. Trouble is I really don't know how to implement the Unique ID 
system you speak of. I might have to do some serious reading before 
advancing much from here. Any suggested reading or example code I 
could look at?

Many thanks.
