My system is behind a firewall and I've had to set my proxy in Eclipse and that all works fine except for when I try to run anything in the "Execute Anonymous" tab.

I believe this is due to the proxy set in Eclipse not being picked up as it has the same response as it was trying without setting the proxy.

Anyone else come across this issue?

The errors I get are:

first a window titled
"Exception Occurred"
com.sforce.ws.ConnectionException

Then further details in the results box show:
