Hi, I can't tell why exactly you're getting a null reference exception since you didn't provide enough information; look at the line numbers, maybe it is because browser is still null. I suggest you read two of my articles: the latest one on cross-thread problems, and the one on Visual Studio tricks. See sig below. :)
