While working with Brian’s on this, I reinstalled Build 60 and it’s working properly now. I’m including the following details in case it helps someone else.
At one point in the process, Brian asked me to generate the “C:\wdisplay\databackup\wdisplayftp.reg” file using the command from the menu bar: “Action → Back Up Window Registry Entries”. Before trying to reinstall Build 60, I double-clicked that file, which restores those entries. Also, I ran the registry clean-up tool from Piriform’s CCleaner software prior to generating the *.reg file. I don’t know if either of these actions caused it to start working properly, but it’s working now! Thank you, Brian.
