This has driven me to the point of insanity :)
When I wake my computer up and try to dial-up, I get this nice dialog:
Error 813: You have attempted to establish a second broadband connection while a previous broadband connection already established using the same device or port
And then some more bla bla bla. I've searched the net and I'm not the only one having this problem, but there are no solutions!
So, an option of auto-hangup after 30 minutes of idleness while the sleep is after 60 is very acceptable, but a solution that addresses the problem directly would be super.
