My laptop is Windows 7 with IE 11.0.9600.18665 and when I access the BAM portal everything works fine.
BizTalk 2016 is installed on Win 2012/R2, with IE 11.0.9600.18666. But on the Win 2012 server, when I click "Activity Search", select an activity, and then use the "Column Chooser" and click the ">>" button to move the field from the left to the right, nothing happens.
I'm logged on with the same credentials on each. Why would have this issue on the server?
