@DJScottyD : no, doesn't help.
The problems I'm having with 11.2.32 are linked to a large library.
The "trick" with copying the Quicktime DLL didn't help as well.
I already submitted a report to Apple, hopefully they will pick this up. For me at the moment:
11.1 = OK with large libraries (> 500 GB) and Windows 8.1 x64
11.2 = NOT OK with large libraries (> 500 GB) and Windows 8.1 x64
11.2 after a fresh install works ok, even with some songs in your library. I didn't check where things go wrong.
I have seen similar reports on the OS X side of things, so perhaps it's in their database code.
Makes you wonder.. whether they test these "performance optimizations and bug fixes"....
