Problem: When using VPN to download a file, my computer becomes 100% non-responsive. I am not able to force/quit any apps nor am I able to restart the computer. The only way to un-hang the computer is to do a hard reset / tun the computer off and on again. Any suggestions as to why this is happening and what I can to do remedy the problem is greatly appreciated. Background: 1. 2008 Macbook Pro with 4Gb RAM. OSX 10.8.3 2. VPN client is Bit Torrent or uTorrent 3. I use BTGuard for VPN services 4. VPN config in OSX is 'standard': PPP for v4 and Automatic for v6; no proxies; no DNS entries; and I check 'ALL TRAFFIC goes VIA VPN' Thanks, in advance for your assistance.
