Oh, I'm quite familiar with both ends of the spectrum. I began my career with computers in 1962 and never stopped. I build computers and write my own utilities and whatnot to cover little niches that big companies don't want to mess with.
I dug deeper into this problem and found through TRACERT that there are several interim servers and trunks that react differently each time I try. It's really a minor irritation but it does happen quite regularly.
Sometimes I can cure it by rapidly clicking between two highlighted in-line comments. Closing and reopening the box will also do the trick. maybe it's the time of day or the phase of the moon.
