Just checked it out. I was having a problem chasing down a memory leak in a Delphi VCL application that used a VirtualTreeview (or possibly 4) and Deleaker was the quickest way to resolve the issue by leading me right to the line in my application that was causing the leak and theen diving even deeper into the system.
I'm using Delphi 10.4.2. I was on 10.4 and it was handy there too.
Thanks, Artem!
