There is a known bug with this version when working in layout mode.
If you're doing a lot of layout work, occasionally quit FileMaker and relaunch.
Hopefully this will be fixed in an update.
That's what I've been doing and that's what I thought. BTW had the same Problem using FMPA 13.
Funny when I called FMI tech support I was told to reinstall the program. If that didn't work, to create a new user.
Why not tell me its a bug.
