I went for the second option, which opens a new instance of IE for me, rather than the first one, which took over existing IE windows that were running (I think you got your descriptions the wrong way around.)

I still need to find out what the difference is here though. I thought system and backticks differed only capturing output. I don't really understand why these calls don't block.

PS Sorry for the delayed reply
