We are using EPESI with several users, some have some strange problems (not all):
Using "Extended Search" in a Adress/Kontakt list:
The first attempt to use Extended search fails, after reloading the same page again it works.
In another contact list the Extended Search is not displayed (after pressing the corresponding button)
In a mask to add data to an adress list:
Some input fields should use a search function while typing into that field.
In the first attempt it is displayed "In der Gitteransicht ist die Suche deaktiviert"
(english: "in the grid view the search function is deactivated")
Again, if you reload the same page (->LaunchPad -> same page again -> Add) / o
n the next try this function is available.
All problems appear with Firefox and Google Chrome as well
