adding a new search object results in an object that does not have that search issue.
i changed no settings that i know of. if i open any QlikView document, the searching on all preloaded objects is just fine, except for Tutorial and TutorialFinal.
For control purposes, I just opened TutorialFinal now (have not opened it before) and tested only the search function on existing fields, it still behaved as described. Then I opened "Call Center" sample, and that one behaves just fine.
It seems the tutorial files are the issue? makes using the tutorial pretty difficult
