Does your sink have a seperate sprayer? On some sinks they still had the diverter valve installed in the faucet,even if oyu did not have one. so when turning on the sink the diverter would block it from coming out of the main spout. so when you turn on your bathroom sink it relieves the pressure enough from the diverter so your main spout will run again.
On Edit: you will also find some post on this subject in the archives, it has been brought up before.
