It seems to work OK for me now too. I removed the ?. and put in the > which was the fix. Thanks! I seriously doubt I would have spotted that syntax error for a long time...
But I also did a 'reupgrade' prior to reading your note and - luckily it hasn't screwed up the board working but it doubled a number of templates the software uses. So - soon I'll have to spend some time with their support forums to try to fix that...
If it's not one thing it's another... I'm sure this will be fun to fix.
But at least it appears the editing problem is gone.
