Well, it’s hard to take this blanket nagging seriously. And statements in capital letters disqualify themselves per se.
Otherwise I agree with Janaka. I am using DXO now for around 5 years and never had to restart the computer because of PL. I can even count the number of app crashes on one hand. Also never had problems with one of my approximately 27500 .dop files.
Only problems in fact I once had, was after updating from PL 3 to version 4. There was indeed a bug, which prevented an update of the database.
But it was a specific problem and at the end fixed.
