The same goes with when I have other applications running, such as MSN or simply browsing the net. The internet will just stop working, for a couple of seconds.
I've been having this problem for the last month or so, and I was more or less hoping it'd go away -- but it hasn't. I've done virus scans, spyware scans, and I've run hijack this and nothing suspicious came up.
Any help would be greatly appreciated. ;x
