By download you apparently mean downgrade?
Yes, you're right. It was typed in haste and slight frustration as we're meant to be celebrating our 25th wedding anniversary in Thailand and there I was having to make a version available that will shortly be 2 versions old as the current version still doesn't work properly.
Apparently this is all down to the use of Classic theme, the recommended solution is to go through every output layout that uses this and change to any other built-in theme.
So, with 30 plus years of FileMaker development behind us, I guess this will take an hour or two! Some of the solutions in place have only taken 10,000 hours to develop.
Don't you just love backwards compatibility?
