Deathadder V2 crashing explorer.exe

Is anyone else experiencing explorer.exe and taskbar hangs and using a Razer mouse? I've seen a few threads over on the keyboard side of things. I can reproduce this every single time by booting up the PC, login to any local account and switch to another account. The taskbar will hang until explorer.exe manages to sort itself out which takes around 5 minutes. The normal solution is to restart. It will very occasionally happen on startup but it happens every single account switch. This behaviour also occurs in safe mode. I'm running the latest firmware, drivers and windows updates. I can completely mitigate this issue by unplugging the mouse before first boot. I have ripped out all mice drivers and Synapse and reinstalled everything, disabling the HID compliant drivers that get installed automatically.
