Running "repair" did not solve the problem, and lately others are complaining of the same issue. Also, possibly related, maybe not, is that when I have a report go to a file and I answer "yes" when it asks if I want the file to be opened for me, it doesn't actually open the file. It is strange that this started when I put TMG on a new computer - same Windows10 version and same TMG version as on the previous computer, but different results.
