I have a portal that is filtered by a global field. It works perfectly the first time in IWP. If I try to select another option from the field the page hangs in edit mode. I cannot submit, cancel or log out. I cannot close filemaker12 normally (I have to force quit). FileMaker asks me to change the IWP port before I can open the file again, unless I reboot the Mac. The setup works fine in FileMaker itself. What am I doing wrong?
