Probably not from here... but I'll try next time I'm in NY. Though it's funny that I imported it three or four times and it still pops up.

IOW, this means there's no way to automate this, just make sure the certificate is accessible to the local machine? That may make this a non-problem, because in the office, where this needs to run, the certificate dialog doesn't pop up, so it's probably already there.

Thanks anyway.
