I have seen that too in regard to Wunderground. It comes up even though it's not scheduled to.
To check on the Wunderground thing,
Click set up then
Internet settings.
If your only uploading one profile for your website you should only have see that one.
If you see one that's not supposed to be there click on configure and delete it.
As for the hang ups with the dial-up not sure what to tell you there. It's been a while since I was on dial-up. A call to Davis tech support may help.
One other thing. Flyingvranch sounds very familiar. Where are you located?
