I have setup "Synchronization" to "Save files on frame deactivation"
This is the onyl option that is checked in "Synchronization" section.
However, while this option works, IDE also saves the file after I switch tabs inside the IDE.
I can easily observe this because the "Gulp" tool which is watching the files, runs two times.
1. on frame deactivation ( as it supposed to)
2. on changing the tab ( switching to a different file tab inside the IDE) <- shouldn't do this.
System: Ubuntu 14.04.3
