Hi Robin,

It looks like we were doing our own URL encoding in CL-Selenium so
I've changed the code to let Drakma do it (which is the correct place
to do it anyway).  Now it should work correctly in every case.

CL-USER> (let* ((selenium:*selenium-driver-url*
"http://localhost:4444/selenium-server/driver")
		(selenium:*selenium-session* (selenium:do-get-new-browser-session
						 "*opera" "http://www.google.com")))
	   (selenium:do-open "http://www.google.com/webhp?hl=en")
	   (print (selenium:do-get-eval "\"Hello, \" + \"JavaScript!\""))
	   (selenium:do-test-complete))

"Hello, JavaScript!"
NIL

I've created a new 0.3 release which includes the fix.

Thanks for noting this problem,
Matt
