When I have my pen display plugged in and turned on I get many: <RI.Hid> Failed to create device file: 20 The process cannot access the file because it is being used by another process. - messages. Each time my whole system locks for 5 - 10 seconds, unfreezes for a few seconds then repeats. As far as I know this wasn't an issue on previous versions. This happens both in editor and in builds.
