Win: That last fix wasn't tested enough. Create a subfolder with the AppID. The previous fix only allowed one dwindows application instance access to Edge. Create a subdirectory under TEMP with the specified or auto-detected ID. This change made me pull the application ID code out of #ifdef BUILD_TOAST.
