I've been using skype 220.127.116.11 on Win7 64bit for several years (with skype out and an online number, international calls and spending plenty of money there btw)
This was the most "updated" version that could run on Win7 64bit without crashing and without the terrible UI changes since version 4.
And now, what do you know, version 18.104.22.168 crashes on Win8 64bit!
I hope your new bosses at Microsoft don't get too pissed off at you guys for making sure people like me never ever upgre to Windows 8 (I am going back to 7 because I'll be damned if I will be forced to use the terrible new skype UI).
Seriously, how difficult is it to put an option in your latest version that allowes to get the OLD 3.6 interface?? why do millions of people who ask for it (and I've seen plenty of talk about this around the net) can't get something so simple?
It's not your job to tell people what they want, it's your job to listen to them and give them what they ask for.
