I didn't try it as a stand-alone so it really makes you wonder... if you're using VVP. My USB logger has never had a comm problem to the extent that others have had.
I wouldn't have noticed the problem if I wasn't busy trying to get WD to reflect the METAR conditions during my snowfall event. I happened to notice my WLink profiles that update every minute were lagging for 5 minutes or so and things weren't updating normally on that site. I rarely check the logs as long as the site updates. Seeing that WD raised my error counts thru the roof got me real curious but even running Wlink alone with VVP gave me a few errors.
I used to roll the WLink updates right into use but not anymore and I doubt I'll ever get rid of either WLink or WD so 5.8.3 it'll be for me.
