FileMaker Pro Advanced 184.108.40.206
OS X 10.11.6
iMac 15,1 (Late 2014 27" Retina)
When working in layout mode tooltips attached to fields do not appear in the info palette. The tooltips are actually there and appear in browse mode.
No such problem in FileMaker 15.
I haven't found a workaround except to revert to FileMaker 15.
