Manually checking for a new version causes the issue too. Locks up for about 5 minutes until it shows error message "Latest Armory Version could not be retrieved, please check..." I can access versions.txt in my browser fine. Checked with wireshark and it doesn't seem to be attempting the connection (although I could be wrong, I don't use it that often). I don't have any firewall except windows which I tried turning off with no effect. I do have python installed separately as well, not sure if that could be causing any issues.
