There are troubles with working more than one developer in a FileMaker 14 solution hosted on a FileMaker server. When more than one developer are in script workspace, you will interfere with each other. When a developer saves a script the others will be interrupted and end up on a new line at the bottom. The same applies when someone saves a layout. The behavior no longer exists in FileMaker 15.
FMPA 14 -> FMS 14 does not work well
FMPA 15 -> FMS 15 work much better
