I have WMP 12.0.9600.17031, which has a weird bug.

With the "Length" column enabled in the Music folder, WMP occupies a whole CPU core; when I close the window the process wmplayer.exe remains running for ~3 minutes before terminating.

Windows Explorer also seems to be suffering: the Music folder is constantly refreshing, making the window flicker, and any right-click menus disappear.

Disabling this column eliminates all of these bugs, and no other columns have this problem.

WHY?????!!!!!!

My specs:

• Intel Core(TM) i7-4510U @ 2.00 - 3.10 GHz
• 8GB DDR3
• 1TB HDD @ 5400 rpm + 8GB SSD cache
• NVIDIA GeForce GT 840M
• Windows 8.1 64-bit (Standard)
• Antivirus: McAfee VirusScan Enterprise 8 
• Latest MRT definitions

I have tried running antivirus scans, MRT, SFC /scannow, defrag etc.

Thanks.
