unrecognized libpcap format error message


I'm running Wireshark within GNS3. When I create a topology in GNS3 and click on a link between, say, two routers and select "Start capture" then Start Wireshark, everything works fine. However, when I stop a capture and try to restart a new capture, I ALWAYS get the message "Unrecognized libpcap format or not libpcap data."

I have tried uninstalling winpcap, rebooting, reinstalling then rebooting again, but the problem persists. How can I fix this? The only work around it to completely stop Wireshark and restart it from within GNS3.

I'm on a Win10 PC running the latest version of Wireshark (v2.6.5).
