Thanks for the quick reply.
Yes, the red update button appeared and I updated. Now the "?" in the connector shows 3.105.
I tested with the "Confirm" dialog and the connector no longer appears beneath it so that's good.
In the case where I was recently getting double attachment with oscillation back and forth I now get no Connector dialog at all.
This is when I use Irfanview (version 4.73 - 64 bit), open a jpg file and then invoke one of the "Save" options. It used to get the connector dialog but now it doesn't.
The save dialog is a bit different from the usual because it has a secondary dialog with options depending on the file type chosen to saving.
