I've been having the same issue with Prism, in that I can't seem to
figure out how to disable quick-find. Where is the "web app" folder
that you are referring to?
Looking in my home directory/Application Data/WebApps/[webapp name]/
there doesn't seem to be a prefs.js file. I then created one however
this did not solve the problem. Are there any other places it should
go? prefs.json? Another directory?
Any help here is definitely appreciated.
