Before installing PGP Desktop 10.1.1 (Build 29) on a corporate Windows 7 Professional 64-bit system, safely remove USB device (e.g. a USB thumb drive) works as expected. After installing PGP Desktop, safely remove for a given USB device works OK until I write something to it, or open a file on the USB drive. Thereafter it consistently reports that "The device is currently in use." and refuses to safely remove. Sample event viewer entry reads..
Device action request for device 'USB\VID_0718&PID_0433\078A1217155A' was vetoed by 'STORAGE\Volume\_??_USBSTOR#Disk&Ven_Imation&Prod_Nano&Rev_PMAP#078A1217155A&0#{53f56307-b6bf-11d0-94f2-00a0c91efb8b}' with veto type 6.
Sysinternals Process Explorer indicates that no processes are locking the device.A work colleague confirms that the same happens to him. The problem only starts happening after PGP is installed.
