--- Comment #2 from Roland Baudin roland65@free.fr --- Hi, same problem here :-(( I attached a patch that implements the CreateThreadPool function (and two others) as stubs. But it doesn't work and Lightroom seems to enter an infinite loop. I guess Lightroom 5.3 really needs these functions to start its threads. It sounds rather strange because Adobe said there were only minor bug fixes in this release... Does anyone know if it would be hard to implement these functions from the thread pool API ? Thx, RB
