When you support an online application, you are supporting the entire computer. This past week, I have troubleshot network connections through VPNs, pop-up blockers in Internet Explorer, and file problems caused by the latest update for MS Office for Macs. Anything that keeps the user from using your system is a problem for you to solve.

I still don’t have a solution on that last one, but I have a workaround.
