Hmmm - I just signed in to Skype, which I haven't done in quite awhile and nothing about upgrading popped up. It connected and all, as expected.

Hmmm - that's a good question. By the way, I'm using version 2.5.0.154. Keep us posted and let us know if anything changes. And maybe someone else who has had/is having this issue will shed some light onto the subject.
