Take a look at the project I sent to you. The records are being added in one
timer and the sorting is taking place in another timer. Timers are NOT
threads; their code runs sequentially, not concurrently. That's what makes
this bug so strange.

In other words, it is NOT that the records are being sorted WHILE more
records are added, it is that the records are being sorted IMMEDIATELY AFTER
more records are added, and records are being added rapidly.

It's all in the project I sent to you. Did you get it?
