[Blind-sysadmins] Run as a different user with JFW

Hi, I am doing an Exchange 2013 upgrade and came across an issue with ActiveSync as I am in the Domain Admins group. I know this is very bad practise, and I wanted to deal with this for a while, so I removed myself from the group, and for the most part am using an admin account to do admin tasks. The issue is with this is that when using one of the snap ins, for example, if I do a run as a different user with JFW, the program launches, but JFW can't read the contents of the window. I can sometimes use the review cursor to get the window, but it isn't reliable. I have been logging in as the separate admin account completely in order to run tasks. Any suggestions as to a better way? Thanks. Andrew.
