Selenium RC Error when running tests

Question

I get this error when running a number of tests in seleniums Bromine, The selenium RC version 1.0.2 outputs this:

WARN - GET /selenium-server/driver/?cmd=testComplete&1=&2=&sessionId=1274d41621c64fc08c1e7ea0a58f260b HTTP/1.0 java.lang.IllegalStateException: unexpected command json={command:"open",target:"/Library/Security/Login.aspx?ReturnUrl=%2fIndex.aspx",value:""} in place before new command selectWindow could be added at org.openqa.selenium.server.CommandQueue.doCommandWithoutWaitingForARe sponse(CommandQueue.java:121)

Any ideas

I'm also seeing this IllegalStateException, much too frequently. Its occurrence seems random, as if something in Selenium isn't synchronized properly. I have seen it several times in connection with a TestNG Listener that calls selenium to do a screen capture, but again, it's unpredictable.
