Open VPN problem

Hello Syndicate,
I'm running Open VPN on a windows 8 laptop. The problem I have is when I disconnect from an Endpoint or exit node then try to reconnect or switch nodes the client will (9 times out of 10 ) take a long time to connect. Once the connection is complete some applications are not able to pass traffic trough the tunnel. I then need to reboot the PC and then reconnect to an exit node.

I am running Open VPN as admin
