I just think that I need to enter a critical section, add item to the list, then leave the critical section.
I am definitely not expert in thread programming, but I am clear about the logic of my class and program. Actually, it is a TTree object I wrote, using TFPList to store sibling nodes. There are a lot of TFPList (one per tree node). I just need to make sure that there are no more than one thread operating on the same node at the same time. Xiangrong
