The problem has been solved in a manner of speaking. To be clear as to what the problem was, any time in 3.71 that you clicked on a Lookup button (the magnifying glass), the above error occurred and the screen closed.
Solution 1 was to replace the ALE files from a good installation..\MAS90\SOA\ Sy1Q01, SY1Q02, SY1Q03, SY1Q04, SY1QDD
This did not work for me.
Solution 2 was to reboot into safe mode. In safe Mode, the error does not occur. That is an indication that one or more programs is running in the background on my system that is causing this error. One or more of the programs that could be the cause are Microsoft Windows Accessibility programs. I can continue to run the 3.71 upgrade utilities in safe mode. Once i get the monkey off my back, I will investigate to find out what program is causing the problem and report back
